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 s
hown below: y = x + 20
y = −x + 2
Which is a correct step to find x and y?
a) Multiply the equations to eliminate y.
b)Add the equations to eliminate x.
c) Write the points where the graphs of the equations intersect the x-axis.
d) Write the points where the graphs of the equations intersect the y-axis.
