5\times 4y-105=6y
Multiply both sides of the equation by 15, the least common multiple of 3,5.
20y-105=6y
Multiply 5 and 4 to get 20.
20y-105-6y=0
Subtract 6y from both sides.
14y-105=0
Combine 20y and -6y to get 14y.
14y=105
Add 105 to both sides. Anything plus zero gives itself.
y=\frac{105}{14}
Divide both sides by 14.
y=\frac{15}{2}
Reduce the fraction \frac{105}{14} to lowest terms by extracting and canceling out 7.
