To solve for у in the equation 1.22*1.7y + 18.32 = 59.8, follow these steps:

First, multiply 1.22 by 1.7:
1.22 * 1.7 = 2.074

Rewrite the equation with the result from step 1:
2.074y + 18.32 = 59.8

Next, subtract 18.32 from both sides of the equation:
2.074y = 41.48

Finally, divide both sides by 2.074 to solve for y:
y = 41.48 / 2.074
y = 20

Therefore, the solution to the equation is у = 20.
