Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{m = 140}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{1.9m + 14 = 2m}[/tex]

Move 2m to right hand side and change it's sign

Similarly, move 14 to left hand side and change it's sign

[tex] \dashrightarrow{ \sf{1.9m - 2m = - 14}}[/tex]

Collect like terms

[tex] \dashrightarrow{ \sf{ - 0.1m = - 14}}[/tex]

Divide both sides by -0.1

[tex] \dashrightarrow{ \sf{ \frac{ - 0.1m} { - 0.1} = \frac{ - 14}{ - 0.1}}} [/tex]

Calculate

[tex] \dashrightarrow{ \sf{m = 140}}[/tex]

Hope I helped!
