An unknown number y is 15 more than an unknown number x. The number y is also x less than 8. The equations to find x and y are shown below.
y = x + 15
y = −x + 8
Which of the following statements 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.
I believe the answer you are looking for is B, because both equations are able to be added with one another. C and D just dont make sense. Hopefully this satisfies you. Good Luck on 8.06 Sigma Notations! :)
