Question

(6x-40°) (5x+10°) (4x+30°)

Answer 1

Step-by-step explanation:

Simplifying

6x + -40 + 5x + 10 + 4x + 30 = 180

Reorder the terms:

-40 + 10 + 30 + 6x + 5x + 4x = 180

Combine like terms: -40 + 10 = -30

-30 + 30 + 6x + 5x + 4x = 180

Combine like terms: -30 + 30 = 0

0 + 6x + 5x + 4x = 180

6x + 5x + 4x = 180

Combine like terms: 6x + 5x = 11x

11x + 4x = 180

Combine like terms: 11x + 4x = 15x

15x = 180

Solving

15x = 180

Solving for variable 'x'.

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

Divide each side by '15'.

x = 12

Simplifying

x = 12
