Question

(9x + 5 ) - (6x +-8)​

Answer 1

Answer:  x = -4.333333333

Step-by-step explanation:

Simplifying

(9x + 5) + -1(6x + -8) = 0

Reorder the terms:

(5 + 9x) + -1(6x + -8) = 0

Remove parenthesis around (5 + 9x)

5 + 9x + -1(6x + -8) = 0

Reorder the terms:

5 + 9x + -1(-8 + 6x) = 0

5 + 9x + (-8 * -1 + 6x * -1) = 0

5 + 9x + (8 + -6x) = 0

Reorder the terms:

5 + 8 + 9x + -6x = 0

Combine like terms: 5 + 8 = 13

13 + 9x + -6x = 0

Combine like terms: 9x + -6x = 3x

13 + 3x = 0

Solving

13 + 3x = 0

Solving for variable 'x'.

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

Add '-13' to each side of the equation.

13 + -13 + 3x = 0 + -13

Combine like terms: 13 + -13 = 0

0 + 3x = 0 + -13

3x = 0 + -13

Combine like terms: 0 + -13 = -13

3x = -13

Divide each side by '3'.

x = -4.333333333

Simplifying

x = -4.333333333
