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
