An unknown number y is 12 more than an unknown number x. the number y is also x less than 17. the equations to find x and y are shown below. y = x + 12 y = −x + 17 which of the following statements is a correct step to find x and y? multiply the equations to eliminate y. 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. add the equations to eliminate x.
