Pls on this one an unknown number y is 20 more than an unknown number x. the number y is also x less than 2. the equations to find x and y are shown below: y = x + 20 y = −x + 2 which is a correct step to find x and y?

We can add the equations together to cancel out the x terms.

y = x + 20

y = −x + 2

2y = 0 + 22

Now we can solve for y.

2y = 22

y = 11

Lastly, we can input this answer into one of the equations and solve for x.

11 = x + 20

-9 = x

So the solution to the equation system is (-9, 11).
