[tex]\text{Formula: } \boxed{5/4n - 7 = m}[/tex]
[tex]\text{ When n = 40, } \boxed{m = 43}[/tex]
[tex]\text{ Isolate for m:}[/tex]
[tex]\text{Begin by dividing both sides by 4/5 (multiply by reciprocal):}[/tex]
[tex]n = 4/5(m + 7 ) \text{ becomes } 5/4n = m + 7[/tex]
[tex]\text{Subtract 7 from both sides to isolate "m"}[/tex]
[tex]5/4n - 7 = m[/tex]
[tex]\text{Substitute n = 40 into the equation to solve for "m":}[/tex]
[tex]5/4(40) - 7 = m\\\\50 - 7 = m\\\\m = 43[/tex]
