Simplify 3-(4x-5)+6.
Leviafan [203]
3 + -4x = 5(x +6)

Re-order the terms:

3 + -4x = 5(6 + x)
3 + -4x = (6 . 5 + x . 5)
3 + -4x = (30 + 5x)

Solving:

3 + -4x = 30 + 5x

Solving for variable "x"

Move all terms containing "x" to the left, all the other terms to the right.

Add "-5x" to each side of the equation.
3 + -4x + -5x = 30 + 5x + -5x

Combine like terms: 
-4x + -5x = -9x
3 + -9x = 30 +5x + -5x

Combine like terms: 
5x + -5x = 0
0 + -9x = 30 +0
3 + -9x = 30

Add "-3" to each side of the equation.
3 + -3 + -9x = 30 + 3

Combine like terms: 
3 + -3 = 0
0 + -9x = 30 + -3
-9x = 30 + -3

Combine like terms: 
30 + -3 = 27
-9x = 27

Divide each side by "-9".
x = -3

Simplifying:
x = -3
