Question

In the following equation, when x=3, what is the value of y? -4x + 3y = 12

Answer 1

Answer:

y = 8

Step-by-step explanation:

-4(3) = -12

to get -12 to 12 you need to add 24 to -12 to make it 12.

so 3 (8) = 24

so -12 + 24 =12

Answer 2

[|] Answer [|]

$\boxed{Y \ = \ 8}$

[|] Explanation [|]

-4x + 3y = 12

Substitute 3 For X:

-4 * 3 + 3y = 12

Multiply The Numbers:

4 * 3 = 12

-12 + 3y = 12

Add 12 To Both Sides:

-12 + 3y + 12 = 12 + 12

Simplify:

3y = 24

3y/3 = 24/3

24 / 3 = 8

Y = 8
