X/2 + X/3 = 4

You need a common denominator for x/2 + x/3. That would be 6. Multiply  x/2 by 3 to get 3x/6 andmultiply x/3 by 2 to get 2x/6.

3x/6 + 2x/6 =4

5x/6 = 4

Multiply both sides of the equation to get 5x = 24   (5x/6 × 6 = 5x and 6 x 4 = 24)

Divide both sides by 5..... 5x/5 = x.   24/5 = 4.80

X= 4.80

Didn't see the fraction problem!

x/2 + x/3 = 4

MULTIPLY EACH SIDE BY 4

1.  4(x/2 + x/3) = 4(4)

2.  4x/2 + 4x/3 = 16  >  make denominator the same

3.  12x/6 + 8x/6 = 16

4.  20x/6  =  16  or   20x/6  =  16/1

5.  DIVIDE BY 20/6 ON BOTH SIDES

6.  x  =  16/1  /  20/6

7.  TAKE THE RECIPROCAL OF 20/6 THEN MULTIPLY

8.  16/1 *  6/20  =  96/20 / 4/4  =  24/5

x  =  24/5
