(8x + 9) + (–6x – 1)

Sagot :

Answer:

5

Step-by-step explanation:

Simplifying

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

Reorder the terms:

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

Remove parenthesis around (9 + 8x)

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

Reorder the terms:

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

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

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

Reorder the terms:

9 + 1 + 8x + -6x = 0

Combine like terms: 9 + 1 = 10

10 + 8x + -6x = 0

Combine like terms: 8x + -6x = 2x

10 + 2x = 0

Solving

10 + 2x = 0

Solving for variable 'x'.

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

Add '-10' to each side of the equation.

10 + -10 + 2x = 0 + -10

Combine like terms: 10 + -10 = 0

0 + 2x = 0 + -10

2x = 0 + -10

Combine like terms: 0 + -10 = -10

2x = -10

Divide each side by '2'.

x = -5

Simplifying

x = -5
