79=11x+13 <br> Solve each equation by using the properties of equality and justify each step
neonofarm [45]

Solution: X=6

Detailed explanation:

In this problem we're asked to find "x" or the unknown.

The first step is to subtract 11x from both sides.

---\mapsto\boldsymbol{-11x+79=13}

Next, subtract 79 from both sides.

---\mapsto\boldsymbol{-11x=-66}

To finish this off, divide both sides by -11.

---\mapsto\boldsymbol{x=6}

Voila! There's our answer!
