Question

F=
4m + 3
m – 1
make m the subject

Answer 1

m =
`(f+1)/(7)`

Explanation:

f = 4m + 3m -1

f = 7m - 1

Adding 1 to both sides

f+1 = 7m

Dividing both sides by 7

m =
`(f+1)/(7)`

Answer 2

m= (f+3)/(f-4)

Explanation:

It is not clear from the question, but I assume it is:

• f= (4m+3)/(m-1)

so the solution is:

• f= (4m+3)/(m-1)
• f(m-1)=4m+3
• fm-f= 4m+3
• fm- 4m= f+3
• m(f-4)= f+3
• m= (f+3)/(f-4)
