Answer:
Simplifying
x + 2(x + -2) + 3x = 35
Reorder the terms:
x + 2(-2 + x) + 3x = 35
x + (-2 * 2 + x * 2) + 3x = 35
x + (-4 + 2x) + 3x = 35
Reorder the terms:
-4 + x + 2x + 3x = 35
Combine like terms: x + 2x = 3x
-4 + 3x + 3x = 35
Combine like terms: 3x + 3x = 6x
-4 + 6x = 35
Solving
-4 + 6x = 35
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 6x = 35 + 4
Combine like terms: -4 + 4 = 0
0 + 6x = 35 + 4
6x = 35 + 4
Combine like terms: 35 + 4 = 39
6x = 39
Divide each side by '6'.
x = 6.5
Simplifying
x = 6.5
