Question

4m + 5n = 25 solve for N

Answer 1

Add -4m to both sides

4m+5n -4m = 25-4m

5n = -4m +25

Divide both sides by 5

5n/5 = -4m+25/5

n = -4/5 m +5

I hope that's help ! If you have questions please let me know

n = -4/5

Answer 2

Isolate n.

First subtract 4m.
5n = 25 - 4m

Divide by 5 to get n by itself.
n = 5 - 4/5m

That's your final answer.
