Question

M+7+(-15m) + 9-17m= 58

Answer 1

`m=-(42)/(31)`

Explanation:

`m+7+\left(-15m\right)+9-17m=58`

Remove brackets:

`m+7-15m+9-17m=58`

Group the similar terms together:

`m-15m-17m+7+9=58`

`-31m+16=58`

Subtract 16 from both sides:

`-31m+16-16=58-16`

`-31m=42`

Divide both sides by -31:

`(-31m)/(-31)=(42)/(-31)`

`m=-(42)/(31)`
