Question

I need to find x to this equation. Please help!

Answer 1

To determine the value of x

`\begin{gathered} \text{ For parallel line } \\ 4x\text{ - 7 = 7x -16 (interior angle are equal) } \\ 4x\text{ -7x = -61 +7 } \\ -3x\text{ = -54} \\ \text{divide both side by -3} \\ (-3x)/(-3)\text{ = }(-54)/(-3) \\ x=18^0 \end{gathered}`

Hence the value of x = 18°
