Answer 2

Let's solve the given equation step by step:

First, let's simplify the expression on the left side of the equation:

(y + 183) ÷ 7 + (219 + 285) ÷ 9

Next, we can simplify each division separately:

(y + 183) ÷ 7 = (1/7)(y + 183) (219 + 285) ÷ 9 = (1/9)(219 + 285)

Now, let's rewrite the equation with the simplified expressions:

(1/7)(y + 183) + (1/9)(219 + 285) = (388 + 357) ÷ 5

To simplify further, let's multiply both sides of the equation by the common denominators, which are 7, 9, and 5:

5 * 7 * 9 * (1/7)(y + 183) + 5 * 7 * 9 * (1/9)(219 + 285) = 5 * 7 * 9 * (388 + 357) ÷ 5

This results in:

45(y + 183) + 35(219 + 285) = 63(388 + 357)

Expanding the expressions:

45y + 45 * 183 + 35 * 219 + 35 * 285 = 63 * 388 + 63 * 357

Now, let's perform the calculations on both sides:

45y + 8235 + 7665 + 9975 = 24544 + 22491

Simplifying:

45y + 25875 = 47035

Subtracting 25875 from both sides:

45y = 21160

Finally, dividing both sides by 45:

y = 21160/45

y ≈ 470.22

Therefore, the value of y that satisfies the equation is approximately 470.22.
