Solve this equation: – 7x + 12 – 2x = 23 + 13x
-7x+12-2x =
23+13%
Step 1: Simplify by combining like terms that are on the
same side of the equation. Which terms can be
combined? -7x and -2x
- 9x+12 =
-23
23+13x
-23
Step 2: Both sides of the equation contain a variable term. It
is possible to isolate the variable term on either the
left or right side of the equation. How would you like
to isolate the variable term?
-9x-11 =
+ 9x
+13x
+9x
-11 =
+ 22
+22x
= 22
Subtract 23
from both sides of the equation.
Step 3: Isolate the variable term on one side of the equation
by adding 9x to
both sides of the equation.
Correct Dividing both sides by 22
