Answer: y = 4
Step-by-step explanation: To solve for y, we must first isolate the term containing y which in this problem is -6y.
Since 4 is being added to -6y, we subtract 4
from both sides of the equation to isolate the -6y.
On the left, the +4 and -4 cancel out
and on the right, -20 - 4 is -24.
So we have -6y = -24.
Now we can finish things off by just dividing
both sides of the equation by -6.
On the left the -6's cancel and on
the right, -24 divided by -6 is 4.
So we have y = 4 which is the solution to this equation.
