Well, I would just reverse it. It seems you just have to reverse the whole problem.
Answer:
x= -3
Step-by-step explanation:
7+
= 5
21+2x=15
2x=-6
x= -3
17(x + 5)
to find a equivalent expression, simplify this one
distribute the 17 to both x and 5 (distributive property)
17(x) = 17x
17(5) = 85
17x + 85 is your simplified and equivalent expression
hope this helps
Answer:
-27
Step-by-step explanation:
5x + 15 = 4x -12
5x - 4x = -12 - 15
x = -27
