To solve for у, we can start by simplifying the equation:
1.2 + 3/10 у = 8/15 у + 0.78
First, let's get rid of the fractions by multiplying every term by the LCD (Least Common Denominator) of 10, 15, and 3 which is 30:
30(1.2) + 30(3/10 у) = 30(8/15 у) + 30(0.78)
30.0 + 9у = 16у + 23.4
Now, let's isolate у by moving the terms involving у to one side of the equation and the constants to the other side:
9у - 16у = 23.4 - 30.0-7у = -6.6
Now, divide by -7 on both sides:
у = -6.6 / -7у = 0.9428571428571428
Therefore, у = 0.9428571428571428.
