Answer:
Simplifying
25 + -1(3x + 5) = 2(x + 8) + x
Reorder the terms:
25 + -1(5 + 3x) = 2(x + 8) + x
25 + (5 * -1 + 3x * -1) = 2(x + 8) + x
25 + (-5 + -3x) = 2(x + 8) + x
Combine like terms: 25 + -5 = 20
20 + -3x = 2(x + 8) + x
Reorder the terms:
20 + -3x = 2(8 + x) + x
20 + -3x = (8 * 2 + x * 2) + x
20 + -3x = (16 + 2x) + x
Combine like terms: 2x + x = 3x
20 + -3x = 16 + 3x
Solving
20 + -3x = 16 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
20 + -3x + -3x = 16 + 3x + -3x
Combine like terms: -3x + -3x = -6x
20 + -6x = 16 + 3x + -3x
Combine like terms: 3x + -3x = 0
20 + -6x = 16 + 0
20 + -6x = 16
Add '-20' to each side of the equation.
20 + -20 + -6x = 16 + -20
Combine like terms: 20 + -20 = 0
0 + -6x = 16 + -20
-6x = 16 + -20
Combine like terms: 16 + -20 = -4
-6x = -4
Divide each side by '-6'.
x = 0.6666666667
Simplifying
x = 0.6666666667
