Solve for the equation for y: 3/2 y + 12 = 7/5 y-20

29/10y=-32

Step-by-step explanation:simply find a common denominator in this case ten add them together and subtract 12 to -20 and your done

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
