HELP!!! could you do it in steps? find x ;
x+2/3 = 2x+1/2
x+2/3 = 2x+1/2

Find a number that all the denominators go into (2 and 3 both go into 6) so multiply everything by 6:
6(x+2)/3 = 6(2x+1)/2
Now simplify the fractions:
2(x+2) = 3(2x+1)
Expand the brackets:
2x + 4 = 6x + 3
Subtract 4 from both sides:
2x = 6x - 1
Subtract 6x from both sides:
-4x = -1
Divide both sides by -4:
x = 1/4
6(x+2)/3 = 6(2x+1)/2
Now simplify the fractions:
2(x+2) = 3(2x+1)
Expand the brackets:
2x + 4 = 6x + 3
Subtract 4 from both sides:
2x = 6x - 1
Subtract 6x from both sides:
-4x = -1
Divide both sides by -4:
x = 1/4

(x+2)/3 = (2x+1)/2
here you can multiply through by 6 to get rid of the fractions
[always get rid of the fractions]
when you get into more interesting equations, you will have binomials for denominators
so
multiply through by 3
(x+2) = 3(2x+1)/2
multiply through by 2
2(x+2) = 3(2x+1)
distribute into the parentheses
(2x+4)=(6x+3)
1=4x
x=1/4

(x+2)/3 = (2x+1)/2
Find the Least Common Denominator (LCD) which is 6.
2(x+2)/6 = 3(2x+1)/6
2(x+2) = 3(2x+1)
2x+4 = 6x+3
4-3=6x-2x
1=4x
x=1/4 or 0.25
Test:
(0.25+2)/3 = (2[0.25]+1)/2
2.25/3 = 1.5/2
0.75 = 0.75
x is confirmed (=) 0.25.

Cross-multiply.
3(2x + 1) = 2(x + 2)
6x + 3 = 2x + 4
4x + 3 = 4
4x = 1
x = 0.25
I hope this information was very helpful.
