30 what is the solution for the system of equations? use the substitution method to solve. 2x+y=20 −5y=−6x+12 enter your answer in the boxes.

x=7 and y=6

Explanation:

We have been given with the equation 2x+y=20          (1)

And -5y = -6x+12  it can be written as -5y+6x=12             (2)

Now we can get the value of y in terms of x from equation (1) we get y = 20-2x    

Now substitute y =20-2x in equation (2)

we will get -5(20 -2x)+6x=12  after simplifying we will get

-100 +10x +6x=12

On further simplification  16x =112   then we will get

x=7

Now substitute x=7 in equation y = 20-2x

y = 20 -2(7)

y=6

Hence, x=7 and y =6

it could be 1,3 and more others to create a cylinder.
