Answer:
m=5
Step-by-step explanation:
We can solve this by using a system of equations. The easiest way to solve this is by using substitution.
3m=19-n Subtract both sides by 19 to find n.
-19 -19
3m-19=-n Divide everything by -1 to make n positive.
/-1 /-1
n=-3m+19
Now, we can substitute n into the second equation.
2m+5(-3m+19)=30 Substitute (-3m+19) into n.
2m-15m+95=30 Simplify.
-13m+95=30 Simplify and subtract both sides by 95.
-95 -95
-13m=-65 Divide both sides by -13.
/-13 /-13
m=5
We don't need to solve for n at all, so that is the answer!
Hope this helps, and have an amazing day ♥
