Question

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?

Add the equations to eliminate p.
Multiply the equations to eliminate w.
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.

Answer 1

hint: p + (-p) = 0
when we add the two equations together, p gets eliminated

Answer 2

So a?

Answer 3

yea

Answer 4

thank you :)
