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?

multiply the equations to eliminate y.

add the equations to eliminate x.

write the points where the graphs of the equations intersect the x-axis.

write the points where the graphs of the equations intersect the y-axis.
