Simplifying
2x + 4 + -1(1000 + 4x) + 50 = 9x + 40 + 2 + -3 + 2x
2x + 4 + (1000 * -1 + 4x * -1) + 50 = 9x + 40 + 2 + -3 + 2x
2x + 4 + (-1000 + -4x) + 50 = 9x + 40 + 2 + -3 + 2x
Reorder the terms:
4 + -1000 + 50 + 2x + -4x = 9x + 40 + 2 + -3 + 2x
Combine like terms: 4 + -1000 = -996
-996 + 50 + 2x + -4x = 9x + 40 + 2 + -3 + 2x
Combine like terms: -996 + 50 = -946
-946 + 2x + -4x = 9x + 40 + 2 + -3 + 2x
Combine like terms: 2x + -4x = -2x
-946 + -2x = 9x + 40 + 2 + -3 + 2x
Reorder the terms:
-946 + -2x = 40 + 2 + -3 + 9x + 2x
Combine like terms: 40 + 2 = 42
-946 + -2x = 42 + -3 + 9x + 2x
Combine like terms: 42 + -3 = 39
-946 + -2x = 39 + 9x + 2x
Combine like terms: 9x + 2x = 11x
-946 + -2x = 39 + 11x
Solving
-946 + -2x = 39 + 11x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-11x' to each side of the equation.
-946 + -2x + -11x = 39 + 11x + -11x
Combine like terms: -2x + -11x = -13x
-946 + -13x = 39 + 11x + -11x
Combine like terms: 11x + -11x = 0
-946 + -13x = 39 + 0
-946 + -13x = 39
Add '946' to each side of the equation.
-946 + 946 + -13x = 39 + 946
Combine like terms: -946 + 946 = 0
0 + -13x = 39 + 946
-13x = 39 + 946
Combine like terms: 39 + 946 = 985
-13x = 985
Divide each side by '-13'.
x = -75.76923077
Simplifying
x = -75.76923077
