Question

look at the diagram. which equation can be used to solve for x? 8x + 90 = 180 8x + 113 = 180 8x + 71 = 180 8x + 132 = 180 solve for x. x =

Explanation:

Step1: 确定方程

已知$8x + 71=180$。

Step2: 求解x

对$8x + 71=180$进行移项可得$8x=180 - 71$，即$8x = 109$，那么$x=\frac{109}{8}=13.625$。

Answer:

$13.625$
