simplify 36 - 4.5x + 36 to -4.5x + 72
simplify 102 - 7.5x - 60 to -7.5x + 42
add 7.5x to both sides
simplify -4.5x + 72 + 7.5x to 3x + 72
subtract 72 from both sides
simplify 42 - 72 to -30
divide both sides by 3
simplify 30/3 to 10
Answer: x = -10
simplify 36 - 4.5x + 36 to -4.5x + 72
simplify 102 - 7.5x - 60 to -7.5x + 42
add 7.5x to both sides
simplify -4.5x + 72 + 7.5x to 3x + 72
subtract 72 from both sides
simplify 42 - 72 to -30
divide both sides by 3
simplify 30/3 to 10
Answer: x = -10
Answer:
The solution is x=-10.
Step-by-step explanation:
4.5*8-4.5x+36=102-2.5*3x-2.5*24
36-4.5x+36=102-7.5x-60
72-4.5x=42-7.5x
72-42=-7.5x+4.5x
30=-3x
30/ (-3) =-3x/ (-3)
x=-10
