Answer 1

`m=2\\\\w=77`

Explanation:

`4.6=4m-3.4`

Solve for m. Add 3.4 to both sides:

`4.6+3.4=4m-3.4+3.4\\\\8=4m`

Isolate the variable. Divide both sides by 4:

`(8)/(4)=(4m)/(4)\\\\ m=2`

`(w)/(7) -2=9`

Solve for w. Add 2 to both sides:

`(w)/(7)-2+2=9+2\\\\ (w)/(7)=11`

Isolate the variable. Multiply both sides by 7:

`7((w)/(7))=7(11)\\\\w=77`
