Answer 2

`\bf r=0`

Explanation:

`\bf -2r+15=-3\left(-2r-7\right)-6`

Expand: *-3(-2r-7)-6 = 6r+15* :-

`\bf -2r+15=6r+15`

Subtract 6r from both sides:-

`\bf -2r+15-6r=6r+15-6r`

`\bf -8r+15=15`

Subtract 15 from both sides:-

`\bf -8r+15-15=15-15`

`\bf -8r=0`

Divide both sides by -8:-

`\bf \cfrac{-8r}{-8}=\cfrac{0}{-8}`

`\bf r=0`
