Question

find the x value in (3x+15)°+(2x-10)°=180°​

Answer 1

Answer:41

Step-by-step explanation:Simplifying

3x + -15 + 2x + -10 = 180

Reorder the terms:

-15 + -10 + 3x + 2x = 180

Combine like terms: -15 + -10 = -25

-25 + 3x + 2x = 180

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

-25 + 5x = 180

Solving

-25 + 5x = 180

Solving for variable 'x'.

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

Add '25' to each side of the equation.

-25 + 25 + 5x = 180 + 25

Combine like terms: -25 + 25 = 0

0 + 5x = 180 + 25

5x = 180 + 25

Combine like terms: 180 + 25 = 205

5x = 205

Divide each side by '5'.

x = 41

Simplifying

x = 41
