Question

25°+(2x+15)°+180°
help me please

Answer 1

Answer:

Simplifying

2x + 15 + 3x + -25 = 180

Reorder the terms:

15 + -25 + 2x + 3x = 180

Combine like terms: 15 + -25 = -10

-10 + 2x + 3x = 180

Combine like terms: 2x + 3x = 5x

-10 + 5x = 180

Solving

-10 + 5x = 180

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 + 5x = 180 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 180 + 10

5x = 180 + 10

Combine like terms: 180 + 10 = 190

5x = 190

Divide each side by '5'.

x = 38

Simplifying

x = 38
