Answer 2

Let's solve the equations step by step:

1. 13*(7-5y) = 5*(3-12y)

To simplify, let's expand the expressions on both sides:

91 - 65y = 15 - 60y

Now, let's combine like terms:

-65y + 60y = 15 - 91

-5y = -76

Finally, solve for y by dividing both sides by -5:

y = -76 / -5

y = 15.2

Therefore, the solution for the equation is y = 15.2.

2. 9*(3y+1) = 5*(2y+12)

Let's simplify by expanding the expressions:

27y + 9 = 10y + 60

Now, let's combine like terms:

27y - 10y = 60 - 9

17y = 51

Solve for y by dividing both sides by 17:

y = 51 / 17

y = 3

Therefore, the solution for the equation is y = 3.
