Question

Find q4(q - 15) = 20

Answer 1

q = 20

Step-by-step explanation

Given equation:

`4(q-15)=20`

The first step in finding q is open the parenthesis:

`\begin{gathered} 4* q-4*15=20 \\ 4q-60=20 \end{gathered}`

Add 60 to both sides of the equation:

`\begin{gathered} 4q-60+60=20+60 \\ 4q=80 \end{gathered}`

Finally, divide both sides by 4 to get q:

`\begin{gathered} (4q)/(4)=(80)/(4) \\ q=20 \end{gathered}`
