Question

F= 4m + 3 m – 1 make m the subject

Answer 1

Answer:

m = $\frac{f+1}{7}$

Step-by-step explanation:

f = 4m + 3m -1

f = 7m - 1

Adding 1 to both sides

f+1 = 7m

Dividing both sides by 7

m = $\frac{f+1}{7}$

Answer 2

Answer:

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

Step-by-step 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)
