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

[|] 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
