What is an equation?
"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
We have been given an equation 3x + (8x + 15) =180
We need to solve given equation to find the value of x.
⇒ 3x + (8x + 15) = 180
⇒ (3x + 8x) + 15 = 180
⇒ 11x + 15 = 180
⇒ 11x = 180 - 15
⇒ 11x = 165
⇒ x = 15
Therefore, the value of x is 15.
