Answer 2

To solve the equation (12/15 + x/15) - 4 = 3 8/15, we'll follow these steps:

Step 1: Simplify the expression on the left-hand side by finding a common denominator for the fractions. The common denominator in this case is 15.

(12/15 + x/15) - 4 = 3 8/15

Step 2: Add the fractions on the left-hand side.

(12 + x)/15 - 4 = 3 8/15

Step 3: Convert the whole number on the right-hand side to a fraction with the same denominator.

(12 + x)/15 - 60/15 = 3 8/15

Step 4: Subtract the fractions on the left-hand side.

(12 + x - 60)/15 = 3 8/15

Step 5: Simplify the fraction on the right-hand side.

(12 + x - 60)/15 = (45 + 8)/15

Step 6: Combine like terms on the left-hand side.

(x - 48)/15 = 53/15

Step 7: Multiply both sides of the equation by 15 to eliminate the denominators.

15 * (x - 48)/15 = 15 * (53/15)

x - 48 = 53

Step 8: Solve for x by adding 48 to both sides.

x = 53 + 48

x = 101

Therefore, the solution to the equation is x = 101.
