Question

Find the value of x
14x-15 and 139 degrees (look at the image)

Answer 1

Answer: x=4

Explanation:

Simplifying

(14x + -15) + 139 = 180

Reorder the terms:

(-15 + 14x) + 139 = 180

Remove parenthesis around (-15 + 14x)

-15 + 14x + 139 = 180

Reorder the terms:

-15 + 139 + 14x = 180

Combine like terms: -15 + 139 = 124

124 + 14x = 180

Solving

124 + 14x = 180

Solving for variable 'x'.

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

Add '-124' to each side of the equation.

124 + -124 + 14x = 180 + -124

Combine like terms: 124 + -124 = 0

0 + 14x = 180 + -124

14x = 180 + -124

Combine like terms: 180 + -124 = 56

14x = 56

Divide each side by '14'.

x = 4

Simplifying

x = 4
