200 x 789 = 157800
789 multiplied by 45 is 35,505.
789 x 789 = 622521.
Zero out the Y to find X 3X - 2(0) = -789 3X = -789 X = -263 ------------- now to check you need to find Y, so zero out X 3(0) - 2Y = -789 - 2Y = - 789 Y = 394.5 0r 394 and 1/2 convert to fraction = 789/2 ------------ check 3(-263) - 2(789/2) = -789 -789 - 2(789/2) = -789 cancel one 2 and multiply through by that 2 -1578 + 789 = - 789 -789 = - 789 checks
