Question

19 + 1.5(10m – 8) = 127

Answer 1

`m=8`

Explanation:

`19 + 1.5(10m-8) = 127`

Multiply both sides by 10

`190+15(10m-8)=1270`

Subtract 190 from both sides

`15(10m-8)=1080`

Divide both sides by 15

`10m-8=72`

Add 8 to both sides

`10m=80`

Simplify

`m=8`

Answer 2

`19+1,5(10m-8)=127\\\\19+15m-12=127\\\\15m+7=127 \ \ /-7\\\\15m=120 \ \ /:15\\\\\huge\boxed{m=8}`
