-6y-6+8y=2\left(y-3\right)
Use the distributive property to multiply -6 by y+1.
2y-6=2\left(y-3\right)
Combine -6y and 8y to get 2y.
2y-6=2y-6
Use the distributive property to multiply 2 by y-3.
2y-6-2y=-6
Subtract 2y from both sides.
-6=-6
Combine 2y and -2y to get 0.
\text{true}
Compare -6 and -6.
y\in \mathrm{C}
This is true for any y.
-6y-6+8y=2\left(y-3\right)
Use the distributive property to multiply -6 by y+1.
2y-6=2\left(y-3\right)
Combine -6y and 8y to get 2y.
2y-6=2y-6
Use the distributive property to multiply 2 by y-3.
2y-6-2y=-6
Subtract 2y from both sides.
-6=-6
Combine 2y and -2y to get 0.
\text{true}
Compare -6 and -6.
y\in \mathrm{R}
This is true for any y.
