ANSWER NOW PLEEEEEEEEEAAAAAAASSSSSSSEEEEEE
All i need to know is what to divide, add, subtract or multiply by the know how you got that method and the know what M is equal to
Is this what you need?
9/2m - 8 = - 5.5 + 4m
9/2m = -5.5 + 8 + 4m
9/2m - 4m = 2.5
4 1/2m - 4m = 2.5
1/2m = 2.5
m = 2.5 / (1/2)
m = 2.5 / 0.5
m = 5
To check this answer, substitute 5 for m in the original problem.
What I'd advise is to balance the equation. What you do on one side of the equal sign, do it on the other.
9/2m-8= -5.5 + 4m
9/2m = 4 1/2m
4 1/2m -8= -5.5 + 4m
Add 8 on both sides
4 1/2m = 2.5 + 4m
Subtract 4m on both sides
1/2m = 2.5
Multiply 2 on both sides
m=5
ok now i need
1/3p + 7 = 12 - 2/3p
