Answer:

y= −5 /2  or y=1

Step-by-step explanation:

Step 1: Cross-multiply.

8 /5+3y = 6y−1 /5

(8)*(5)=(6y−1)*(5+3y)

40=18y^2+27y−5

Step 2: Subtract 18y^2+27y-5 from both sides.

40−(18y^2+27y−5)=18y^2+27y−5−(18y^2+27y−5)

−18y2−27y+45=0

Step 3: Factor left side of equation.

−9(2y+5)(y−1)=0

Step 4: Set factors equal to 0.

2y+5=0 or y−1=0

y= −5 /2  or y=1

Answer:

y= −5 /2  or y=1
