Step-by-Step Solution

To solve for x x in the equation 23x+14x15x+12x=2 \frac{2}{3}x+\frac{1}{4}x-\frac{1}{5}x+\frac{1}{2}x=2 , we will follow these steps:

Step 1: Combine the coefficients of x x by finding a common denominator.
- The denominators are 3, 4, 5, and 2. The least common multiple (LCM) of these is 60.
- Rewrite each term with a denominator of 60:
23x=4060x\frac{2}{3}x = \frac{40}{60}x, 14x=1560x\frac{1}{4}x = \frac{15}{60}x, 15x=1260x\frac{1}{5}x = \frac{12}{60}x, 12x=3060x\frac{1}{2}x = \frac{30}{60}x.

Step 2: Combine the fractions:
- Combine to get: 4060x+1560x1260x+3060x=7360x.\frac{40}{60}x + \frac{15}{60}x - \frac{12}{60}x + \frac{30}{60}x = \frac{73}{60}x.

Step 3: Set up the equation and solve for x x :
- The equation becomes 7360x=2\frac{73}{60}x = 2.
- Multiply both sides by 6073\frac{60}{73} to isolate x x :
x=2×6073 x = 2 \times \frac{60}{73} .

Therefore, x=12073 x = \frac{120}{73} .

Answer

12073 \frac{120}{73}
