Question

What is the answer of the problem

Answer 1

7x+8-9x=22
-8 on both sides
+8-8 cancels out
22-8 is 14
7x-9x=14
subtract like terms
7x-9x=-2x

-2x=14
14 divided by -2

-2 divided by -2 cancles out

14 divided by -2=-7

x=-7

Answer 2

Solve for x:
8 - x = 22
Subtract 8 from both sides:
(8 - 8) - x = 22 - 8
8 - 8 = 0:
-x = 22 - 8
22 - 8 = 14:
-x = 14
Multiply both sides of -x = 14 by -1:
(-x)/(-1) = -14
(-1)/(-1) = 1:
Answer: x = -14
