Question

solve - 2x+30° + 3x-20°=180°​

Answer 1

Answer:

Simplifying

2x + 30 + 3x + -20 = 180

Reorder the terms:

30 + -20 + 2x + 3x = 180

Combine like terms: 30 + -20 = 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 = 170

5x = 170

Divide each side by '5'.

x = 34

Simplifying

x = 34
