Solve for x. 5(x - 10) = 30 – 15xA. x = 1 B. x = 4 C. x = 5 D. x = 8
2 answers:
x=4
Step-by-step explanation:
Distrubutive property: 5x-50=30-15x
get x on one side: 5x-50+15x=30
combine like terms: 20x-50=30
subtract on both sides: 20x=30+50
20x=80
simplify: 20/20=80/20
x=4
5x - 50 = 30 - 15x
30+50= 80
-15x - 5x = -20x
-20x = 80
20/80
