-3(b – 7)
= (-3)(b) + (-3)(-7)
= -3b + 21
6. Solve the equation. Show your work. Check your answer. 3x – 7 = 5x + 19
Weegy: 3x – 7 = 5x + 19 , 3x - 5x = 19+7, -2x = 26, - x=26/2, x=-13 (More)

3x – 7 = 5x + 19
3x - 5x = 19 + 7
-2x = 26
x = 26/-2
x = -13

3(-13) – 7 = 5(-13) + 19
-39 - 7 = -65 + 19
-46 = -46
Weegy: 4y + 5 = – 31 , 4y= -31-5, 4y=-36, y=(-36/4), y=-9 (More)

4y + 5 = – 31
4y = -31 - 5
4y = -36
y = -36/4
y = -9

4(-9) + 5 = – 31
-36 + 5 = -31
-31 = -31
