Given the equation:
2(x+2)+2(x+4)=28
Determine how many inches.
Solution:
Since we are asked to determine how many inches, then we can assume that x = measurement in inches. In this case, we need to solve for x. The first step is to distribute 2 to their corresponding parenthesis.
2(x+2)+2(x+4)=28
2x + 4 + 2x + 8 = 28
4x + 12 = 28
Transpose 12 on the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
4x = 28 - 12
4x = 16
Divide both sides by 4 in order to cancel out 4x, leaving behind x.
4x/4 = 16/4
x = 4
Final answer:
x =4
