Question

(6x±9)-(5x-7) full answer

Answer 1

Simplifying 5x + -7 = 6x + -9
Reorder the terms: -7 + 5x = 6x + -9
Reorder the terms: -7 + 5x = -9 + 6x
Solving -7 + 5x = -9 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
-7 + 5x + -6x = -9 + 6x + -6x
Combine like terms: 5x + -6x = -1x -7 + -1x = -9 + 6x + -6x
Combine like terms: 6x + -6x = 0 -7 + -1x = -9 + 0 -7 + -1x = -9
Add '7' to each side of the equation.
-7 + 7 + -1x = -9 + 7
Combine like terms: -7 + 7 = 0 0 + -1x = -9 + 7 -1x = -9 + 7
Combine like terms: -9 + 7 = -2 -1x = -2
Divide each side by '-1'.
x = 2
Simplifying x = 2
