Question

1. create a two - step equation whose solution is x = 6.9. solve for x: 7x + 2 = 30. show your work.10. a rectangles length is x and its width is 4. if the perimeter is 20, write and solve a two - step equation to find the length.

Explanation:

Step1: Subtract 2 from both sides

$$\begin{align*} 7x+2-2&=30 - 2\\ 7x&=28 \end{align*}$$

Step2: Divide both sides by 7

$$\begin{align*} \frac{7x}{7}&=\frac{28}{7}\\ x&=4 \end{align*}$$

Answer:

\(x = 4\)
