Answer 3

To solve the equation 7 1/3 - x = 2 4/5 + 3 7/10, we need to simplify the mixed numbers and then isolate the variable x.

Step 1: Simplify the mixed numbers. 7 1/3 = (3 * 7 + 1) / 3 = 22/3 2 4/5 = (5 * 2 + 4) / 5 = 14/5 3 7/10 = (10 * 3 + 7) / 10 = 37/10

The equation becomes: 22/3 - x = 14/5 + 37/10

Step 2: Find a common denominator. The common denominator for 3, 5, and 10 is 30.

Rewrite the equation with the common denominator: (22/3) * (10/10) - x = (14/5) * (6/6) + (37/10) * (3/3) (220/30) - x = (84/30) + (111/30)

Step 3: Combine like terms. 220/30 - x = (84 + 111) / 30 220/30 - x = 195/30

Step 4: Simplify both sides of the equation. 220/30 - x = 195/30 (220 - x * 30) / 30 = 195/30

Step 5: Eliminate the denominators. 220 - x * 30 = 195

Step 6: Solve for x.

• x * 30 = 195 - 220
• x * 30 = -25 x = -25 / -30 x = 5/6

Therefore, the solution to the equation 7 1/3 - x = 2 4/5 + 3 7/10 is x = 5/6.
