Don't forget that if you have a number in front of a bracket, all the terms within the brackets concerned have to be multiplied by the number.
Eg:
2(x+1) = 2*x + 2*1 = 2x + 2

How to solve the following math question:
x + (2x - 15) + 3(x + 17) = 180
First step: Distribute the 3 to all the values in the correlating parenthesis: x + (2x - 15) + 3x + 51 = 180.
Second: Remove parenthesis: x + 2x - 15 + 3x + 51 = 180.
Third: Combine like terms: 6x + 36 = 180.
Fourth: Isolate the x term: 6x = 144.
Fifth: Solve for x by dividing both sides by 6: x = 24.
Answer: x = 24.
