(08.06) 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? (4 points) multiply the equations to eliminate y. add the equations to eliminate x. * i think its this one 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.
