SOLUTION: Pls help me to solve these 2 problems.Thanks in advance. 1. p=l + m/f Calculate m 2.- x-1/3 + 4x = 2/3 + 13x-2/3 Thanks again

Question 159910: Pls help me to solve these 2 problems.Thanks in advance.
1. p=l + m/f Calculate m
2.- x-1/3 + 4x = 2/3 + 13x-2/3
Thanks again
Answer by ankor@dixie-net.com(22740) (Show Source): You can put this solution on YOUR website!
1. p = l + Calculate m
:
Subtract l from both sides
p - l =
:
Multiply both sides by f
f(p-l) = m
:
:
2. -x-1/3 + 4x = 2/3 + 13x-2/3
:
This is very ambiguous. Assume you mean:
- + 4x = +
Multiply each term by 3, to get rid of the denominators, results
-(x-1) + 3(4x) = 2 + 13x - 2
:
-x + 1 + 12x = 13x; (removing the bracket changes the signs when it's neg)
:
11x + 1 = 13x
:
1 = 13x - 11x
:
2x = 1
x =
:
If this is not what you mean, tell me what you do mean, use brackets.
