(y-40+60) ÷ 3 = 140 × 3

First, simplify the left side of the equation:

(y - 40 + 60) ÷ 3
(y + 20) ÷ 3
y + 20 ÷ 3
y + 6.67

Now, rewrite the equation with the simplified left side:

y + 6.67 = 140 × 3

Next, solve for y:

y + 6.67 = 420

Subtract 6.67 from both sides:

y = 420 - 6.67
y = 413.33

Therefore, the solution to the equation is y = 413.33.
