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.

The given equations are

TO solve for p and w, we can use elimination method. And the first step is to eliminate p by adding both equations .

So out of the given options, correct option is the first option .

 The correct option is (A) Add the equations to eliminate p.

Step-by-step explanation:  Given that 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:

We are to select the correct step to find p and w.

Since the co-efficient of p is 1 and -1 in equations (i) and (ii) respectively, so adding both the equations will eliminate p, and we will get the value of w.

Then, substituting the value of w in any one of the equations will give us the value of p.

So, the system of equations is solved as follows :

Adding equations (i) and (ii), we get

Substituting the value of w in equation (i), we get

Thus, the correct step is the add the equations to eliminate p.

Option (A) is CORRECT.
