Answer:
Step-by-step explanation:
We are going to solve the system by subtracting one equation from another in this case the second from the first.
Now we are going to divide 30 by 6 which will give you the value of x.
Now we will substitute x into one of the equations to solve for y.
Now we multiplied 6 by 5.
Now we will subtract 30 from 60 giving you the value of 2y.
Now you divide 30 by 2 giving you the value of y.
Now check you answers by inserting the values you got for x and y into one of the original .
