Question

The number of steps required to solve the equation $\frac{x}{3}-7=3$ is .

Answer 1

In the equation $\frac{x}{3}-7=3,$ the variable $x$ is being divide by 3 and then 7 is being subtracted. We need to solve x by isolating it on one side of the equation.

Step 1: Add both sides of the equation by 7 to eliminate 7 on the left side of the equation.
$\Rightarrow \frac{x}{3}-7+7=3+7\Rightarrow \frac{x}{3}=10$

Step 2: Now, multiply both sides by 3 to eliminate 3 on the left side of the equation.
$\Rightarrow \frac{x}{3}\times 3=10\times 3\Rightarrow x=30$

Hence, two steps are required to solve the equation $\frac{x}{3}-7=3.$
