Question

Solve each equation.$$2 x+3=7$$

Solve each equation. $$2 x+3=7$$



Answers

Solve each equation.
$$\frac{3 x-2}{7}=\frac{x+2}{5}$$

So we're given this equation over here to x over three minus 70. Cools to x. Sorry. Were given this equation here. So two X over three minus seven is equal to three and raster sulfur x. And so let's add seven to both sides. We get two X or three is equal 10 multiply votes I three and we had two X Is he called a 30 Divide both sides by two. Oh, yeah, X equals 15. And so that right over there is our answer.

We have to solve the linear equation. X plus one, divided by three plus X plus so divided by seven is equal to two now. First, we'll solve the left inside of the equation by taking the CMAs 21 so we'll get seven multiplied with X plus one plus three multiplied with X plus two is equal to talk. No, we'll use the distributive property for the numerator and simplify to get seven X plus seven plus seven plus three X plus six divided by 21 is equal to toe, which gives US 10 X plus 13 divided by 21 is equal to do now, multiplying both equations now multiplying both sides of the equation with 21 will get 10 X plus 13 is equal to 42 which means 10 X is equal to 29 now, dividing both sides off the equation. By 10 we get X as equal to 29 divided by 10. Therefore, the solution is X is equal to 29 divided by 10

Today, we're gonna solve this one step equation. Your X plus seven equals three. What number plus seven equals three? Well, we'll go ahead and use inverse operations here. I want to get rid of that seven. So I know what access. I don't want that. Seven added to it. So the opposite of adding seven is attracting seven. But whatever. I do the one side of the equation one side of the equal sign. I have to do the other s. So I do have to subtract seven from that side. So explosive seven minus seven is X and three minus seven is negative, for that is our solution. We can check our answer. Negative. Four plus seven. Yeah, that would be three.

7.5 is equal to X plus three over to our first step is going to be Get this into an improper fraction. So in order to do that, you mean the multiplied We have seven plus 1/2 so we're going to multiply seven by two over too. And that gives us 14 over two plus 1/2, which is really just equal to 15 over, too. No, you know that we have 15 over to is equal to X plus 3/2. No, we need to solve for X or going to multiply. Both sides fights you to get that out of the denominator and gives us 15 is equal to X plus three reason for that is cancel everything off by twos. These were going to actually cancel each other out. Now, after you subtract three and we get 12 is equal to x
