An unknown number w is 30 more than an unknown number p. The number w is also p less than 5. The equations to find p and w are shown below: w = p + 30
w = −p + 5

Which is a correct step to find p and w? (1 point)

a
Add the equations to eliminate p.

b
Multiply the equations to eliminate w.

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.
