Solve the equation 3x+(8x+15)=180 to find the value of x
kotykmax [81]

Answer:

x=15

Step-by-step explanation:

Simplifying

3x + (8x + 15) = 180

Reorder the terms:

3x + (15 + 8x) = 180

Remove parenthesis around (15 + 8x)

3x + 15 + 8x = 180

Reorder the terms:

15 + 3x + 8x = 180

Combine like terms: 3x + 8x = 11x

15 + 11x = 180

Solving

15 + 11x = 180

Solving for variable 'x'.

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

Add '-15' to each side of the equation.

15 + -15 + 11x = 180 + -15

Combine like terms: 15 + -15 = 0

0 + 11x = 180 + -15

11x = 180 + -15

Combine like terms: 180 + -15 = 165

11x = 165

Divide each side by '11'.

x = 15

Simplifying

x = 15
