Question

-3m = 4m + 14 I'm so confused on how to do it

Answer 1

Hey there! 

Combine your like terms! 

( $-3m$ and $4m$ ) 

Since $4m$ is the greatest one we have to $subtract$ it from each of your sides 

Like: $-3m - 4m \\ = 4m + 14 - 4m$

This gives us: $-7 = 14$

Both numbers are equal to  $7$  , so we have to divide by $-7$ on each of your sides 

$\frac{-7m}{7} (Cancel) \\ \\ = \frac{14}{-7} (Keep)$

Therefore the value of $"m"$ is $-2$

Good luck on your assignment and enjoy your day!

Answer 2

-3m (-4m) = 4m + 14 (-4m)

-3m - 4m = 14 (simplify)

-7m/ -7 = 14/ -7 (isolate the variable)

m = -2 (answer)

hope this helps
