Answer:
12a+8b-28
Step-by-step explanation:
Distribute
4(3a+2b-7)
4×3a=12a
4×2b=8b
4×-7=-28
So
12a+8b-28
Answer:
y – 1= Three-halves(x + 3)
Step-by-step explanation:
line goes through (-2, -4) and (2, 2)
goes through (-3, 1)
slope = (-4 - 2) / (-2 -2) = -6/-4 = 3/2
1 = (3/2)*-3 + b
1 = -9/2 + b
b = 1 + 9/2 = 11/2 = 5.5
y = (3/2)*x + 11/2
(y - 1) = (3/2)(x + 3)

(Hope this helps! Btw, I am the first to answer. If this answer is wrong, I apologize..)
Simplifying
0x + 7 + 5x = 2x + 30 + 40
Anything times zero is zero.
0x + 7 + 5x = 2x + 30 + 40
Combine like terms: 0 + 7 = 7
7 + 5x = 2x + 30 + 40
Reorder the terms:
7 + 5x = 30 + 40 + 2x
Combine like terms: 30 + 40 = 70
7 + 5x = 70 + 2x
Solving
7 + 5x = 70 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
7 + 5x + -2x = 70 + 2x + -2x
Combine like terms: 5x + -2x = 3x
7 + 3x = 70 + 2x + -2x
Combine like terms: 2x + -2x = 0
7 + 3x = 70 + 0
7 + 3x = 70
Add '-7' to each side of the equation.
7 + -7 + 3x = 70 + -7
Combine like terms: 7 + -7 = 0
0 + 3x = 70 + -7
3x = 70 + -7
Combine like terms: 70 + -7 = 63
3x = 63
Divide each side by '3'.
x = 21
Simplifying
x = 21
