Question

79=11x+13 Solve each equation by using the properties of equality and justify each step

Answer 1

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!

Cheers!! ^-^

Answer 2

$\large\green\longrightarrow \tt \large \:79 \: = \: 11x \: + \: 13$

$\large\green\longrightarrow \tt \large \:79 \: - \: 13 \: = \: 11x$

$\large\green\longrightarrow \tt \large \:66 \: = \: 11x$

$\large\green\longrightarrow \tt \large \: \frac{ \cancel{66} \: \: ^{ \pink6} }{ \cancel{11}} \: = \: x$

$\large\green\longrightarrow \tt \large \:6 \: = \: x$

Hence , the value of x is 6
