An unknown number y is 10 more than an unknown number x. the number y is also x less than 3. the equations to find x and y are shown below. y = x + 10 y = –x + 3 which of the following statements is a correct step to find x and y? (4 points) add the equations to eliminate x. 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.
