7-112.
1. Solve each of the following equations for the indicated variable. Homework Help ✎

1. 5x – 3y = 12 for y

2. F = for m2

3. E = mv2 for v

4. (x – 4)2 + (y – 1)2 = 10 for y

Isolate y on one side of the equation.
You can leave coefficients in fraction form.

Start by multiplying by 2 and dividing by m.

$m_{2} = \frac{Fr^2}{Gm_1}$

$(y-1)^2=10-(x-4)^2$

$y-1=\pm\sqrt{10-(x-4)^2}$

$y=\pm\sqrt{10-(x-4)^2}+1$
