how to solve 2(x+4)-1=0
2(x+4) -1 = 0
2x + 8 -1 = 0 Expand brackets 2x + 7 = 0 Collect terms
2x = -7 Minus 7 from both sides
x = -3.5 Devide by 2
I am going to do it a different way as Guest #1 did. :)
\(2(x+4)-1=0\\ 2(x+4)=1\leftarrow\text{Add 1 each side}\\ x+4=\dfrac{1}{2}\leftarrow\text{Divide by 2}\\ x = \dfrac{1}{2}-4 = -3\dfrac{1}{2}\leftarrow\text{Minus 4 each side.ANSWER!!YAAAAY!!}\)
