Question

calculate the value of x 3x - 5° , 65° ,x + 20°​

Answer 1

Step-by-step explanation:

Simplifying

3x + -5 + x + 20 + 65 = 180

Reorder the terms:

-5 + 20 + 65 + 3x + x = 180

Combine like terms: -5 + 20 = 15

15 + 65 + 3x + x = 180

Combine like terms: 15 + 65 = 80

80 + 3x + x = 180

Combine like terms: 3x + x = 4x

80 + 4x = 180

Solving

80 + 4x = 180

Solving for variable 'x'.

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

Add '-80' to each side of the equation.

80 + -80 + 4x = 180 + -80

Combine like terms: 80 + -80 = 0

0 + 4x = 180 + -80

4x = 180 + -80

Combine like terms: 180 + -80 = 100

4x = 100

Divide each side by '4'.

x = 25

Simplifying

x = 25
