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
ANSWER:
x = 24/5
