Answer:
x = 5
Step-by-step explanation:
1/5(3x - 15) = -4(3/5x - 3)
Distribute the 1/5 in.
3x/5 - 3 = -4(3/5x - 3)
Distribute the -4 in.
3x/5 - 3 = -12x/5 + 12
Multiply both sides by 5.
3x - 15 = -12x + 60
Add 15 to both sides.
3x = -12x + 75
Add 12x to both sides.
15x = 75
Divide both sides by 15 to get
x = 5
Proof:
1/5(3x - 15) = -4(3/5x - 3)
1/5(3(5)-15) = -4(3/5(5) - 3)
1/5(15 - 15) = -4(3 - 3)
1/5(0) = -4(0)
0 = 0
