What’s the answer to 1.9m + 14 = 2m?

joja [24]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{m = 140}}}}}$

Step-by-step explanation:

$\sf{1.9m + 14 = 2m}$

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

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

$\dashrightarrow{ \sf{1.9m - 2m = - 14}}$

Collect like terms

$\dashrightarrow{ \sf{ - 0.1m = - 14}}$

Divide both sides by -0.1

$\dashrightarrow{ \sf{ \frac{ - 0.1m} { - 0.1} = \frac{ - 14}{ - 0.1}}}$

Calculate

$\dashrightarrow{ \sf{m = 140}}$

Hope I helped!
