Question

4m − –3m − 17m − –m − –7m = 12 (:

Answer 1

• m= -6

Explanation:

`4m−(−3m)−17m−(−m)−(−7m)=12\\\\\\4m+3m−17m+m+7m=12\\\\\\15m−17m=12\\\\\\−2m=12\\\\\\m=(12)/(-2)\\\\\\\bold{m=-6 }`

Answer 2

Explanation:

`\tt{ 4m-(-3m)-17m-(-m)-(-7m)=12 }` ⠀

`\tt{ 4m+3m-17m+m+7m=12 }` ⠀

`\tt{ 15m-17m=12 }` ⠀

`\tt{ -2m=12 }` ⠀

`\tt{ m=(12)/(-2)}` ⠀

`\tt{m=-6 }` ⠀
