Once you simplify with the combination of like terms and “bringing the baby to the mom” (moving x), you’ll figure out that all real numbers are solutions. Hope this helps!!
2x + 3y = 630 x + y = 245 then you want to get rid of x so in the second equation × by -2 and get -2x -2y =-490 subtract this equation from the first to get y=$140 substitute 140 in for y and get x= $105 and 2x=210 and 3y=420 210 +420=630
