solving two step equations with integers x/5 + 7 =16

Sagot :

Given the equation:

[tex]\frac{x}{5}+7=16[/tex]

Subtract 7 from both sides

[tex]\begin{gathered} \frac{x}{5}+7-7=16-7 \\ \frac{x}{5}=9 \end{gathered}[/tex]

Multiply both sides by 5

[tex]\begin{gathered} 5\cdot\frac{x}{5}=5\cdot9 \\ x=45 \end{gathered}[/tex]
