Explanation: $\downarrow\downarrow\downarrow$

<><><><><><><>

[ Step One ] Replace 3 For X

$\bold{8\cdot \:3-3y=12}$

[ Step Two ] Multiply Numbers: $\bold{8\cdot \:3=24}$

$\bold{24-3y=12}$

[ Step Three ] Subtract 24 From Both Sides

$\bold{24-3y-24=12-24}$

[ Step Four ] Simplify

$\bold{-3y=-12}$

[ Step Five ] Divide Both Sides By -3

$\bold{\frac{-3y}{-3}=\frac{-12}{-3}}$

[ Step Six ] Simplify

$\bold{y=4}$

Answer 2

Answer:

y = 4

Step-by-step explanation:

Plug 3 in for 'x' in the equation and solve for 'y'...

8(3) - 3(y) = 12

   24 - 3y = 12

       -3y = -12

             y = 4
