Solve the given equations. $$\frac{4 x-2(x-4)}{3}=8$$

We need to solve the following equation. So we're going to multiply by the common denominator to get rid of our fractions. We're gonna multiply by eight. So eight times the first one becomes two in parentheses X plus three will distribute later X times the next one becomes minus four times the quantity X minus four equals times the last 18 divided by eight. Just leaves us with our three. So then we distribute two x plus six -4. x plus 16 is equal to three. We combine like terms two X minus four X becomes negative two X. And then we have six plus 16. That becomes plus 22 is equal to three. We subtract 22 from both sides, So 3 -22 is -19. So we get -2 X. is equal to this cancels out negative 19. We divide both sides by -2 and we get X. is equal to positive 19 over to

The same. They give us the equation. Expose 3/4 months in sex menace for over two is equal to 3/8. And what can we do to solve this? Well, I don't know. A Multiply both sides by eight. Let's see. So we'll end up with doubling everything up here so to explosives and then minus almost everything over here by four. So far, ads minus 16 is equal to three. Now let's just review the negative so minus for what? 16 is equal to three. Collect like Tim. So we get negative. Two X plus 22 is equal. It sitting That's odd are two x to the other side and let's subtract are three to the side the but both sides by two and I will see our solutions. That is just 19 over to for this conditional equation over here

We're gonna solve for X pipe first using the inverse of negative four. So you're gonna add 40 both sides donated. Three X is equal to a plus four is 12 a lot of my negative reachable signs, so X will be negative for now. We need to check our word by plugging in your ex. So we have negative three times Negative for minus four is equal to eight. So let's leave the Eagles eight negative three times negative for is positive 12 minus four and it does equal to eight.

To solve this equation. We want to get these variables on the same side of the equal sign. I'm gonna go with the lower of the variables, the negative one x and I'm gonna go ahead and add extra ble sides to cancel it here and added to the other side to keep the equation balanced. If three x plus four it's up three x plus one X is for X and then a plus four. We still have the equals eight on the other side to solve for this ex term. Now I want to get rid of this plus four. So I'm gonna go into the opposite and subtract four from both sides once again to keep the equation balance. So if I subtract for that cancels, I just have the four X equals and eight minus four is for the last step is to notice that this is multiplication and to get X by itself, I have to undo it by dividing. When I divide both sides by four, these four is canceled and I get X equals Ford about it before, which is one
