Question

Solve the equation for the value of x5x + 30 = 90

Answer 1

We are given the following equation

`5x+30=90`

Let us solve this equation for x.

Step 1:

Subtract 30 from both sides of the equation (so that 30 on the left side cancels out)

`\begin{gathered} 5x+30-30=90-30 \\ 5x=60 \end{gathered}`

Step 2:

Divide both sides of the equation by 5 (so that 5 on the left side cancels out)

`\begin{gathered} (5x)/(5)=(60)/(5) \\ x=12 \end{gathered}`

Therefore, the value of x is 12
