Given equation:
[tex]2(x+4)\text{ = 150 + (-2) }[/tex]Open the bracket:
[tex]\begin{gathered} 2x\text{ + 8 = 150 - 2} \\ 2x\text{ + 8 = 148} \end{gathered}[/tex]Collect like terms:
[tex]\begin{gathered} 2x\text{ = 148 - 8} \\ 2x\text{ = 140} \end{gathered}[/tex]Divide both sides by 2:
[tex]\begin{gathered} \frac{2x}{2}\text{ = }\frac{140}{2} \\ x\text{ = 70} \end{gathered}[/tex]Answer:
x = 70
