Answer:
x = 22
Step by step solution:
5x+(3x-18)+x=180
Simplifying
5x + (3x + -18) + x = 180
Reorder the terms:
5x + (-18 + 3x) + x = 180
Remove parenthesis around (-18 + 3x)
5x + -18 + 3x + x = 180
Reorder the terms:
-18 + 5x + 3x + x = 180
Combine like terms: 5x + 3x = 8x
-18 + 8x + x = 180
Combine like terms: 8x + x = 9x
-18 + 9x = 180
Solving
-18 + 9x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 9x = 180 + 18
Combine like terms: -18 + 18 = 0
0 + 9x = 180 + 18
9x = 180 + 18
Combine like terms: 180 + 18 = 198
9x = 198
Divide each side by '9'.
x = 22
