I need to find the value of m in the following equation:

(2m - 1)/3 = 5 + m/6

I am doing a step wrong somewhere and when i reverse to check answer the value is incorrect. Could someone do it step by step so I can see where I'm going wrong? Thanks you!

Be sure you have checked your parenthesis before continuing to ensure you have written the question correctly.

you could break it into separate fractions :

2/3 m -  1/3 = 5 + 1/6 m

get like terms together by subtracting 1/6 m from both sides

2/3 m - (1/6 m) - 1/3 = 5     ----> 1/6 m - 1/6 m =0

then add 1/3 to both sides

2/3 m - 1/6 m = 5 + 1/3   ---> -1/3 + 1/3 = 0

then find common denominators

4/6 m - 1/6 m = 15/3 + 1/3  --> 2/3 * 2/2 = 4/6

5/1 * 3/3 = 15/3

simplify

3/6 m = 16/3

multiply both sides by the reciprocal (flip it) of the coefficient (# in front of m)

6/3 * 3/6 m = 16/3 * 6/3

the fractions cancel each other out  on the left and the right yields 32/3

m = 32/3.

Plug it into original equation and check.

(2m-1)/3=5+m/6

Mutiply 6 both sides:

(2m-1)6/3= (5+m/6)6. simplify

2(2m-1)=30+m

4m-2=30+m.

Subtract m from both sides:

4m-2-m=30+m-m.simplify:

3m-2=30. Add 2 to both sides:

3m-2+2=30+2. simplify:

3m=32

Divide by 3 both sides:

m=32/3 = 10 and 2/3

Substite m=32/3 in original equation:

Left side:

{2*32/3)-1}/3 =  (64/3-1)/3=61/9.

Right side:5+(32/3)/6=5+16/9=(45+16)/9 =61/9.

So,LHS=RHS.

Hope this helps.
