Use elimination to solve each system of equations 3x+2y=0. ,x-5y=17 |
| Answer» 3x+2y=0 ........... (i)x-5y=17 ........... (ii)Multiply equation (ii) by 33x - 15y = 51 ........... (iii)Subtract (i) from (iii), we get3x - 3x -15y -2y = 51-17y = 51y = -51/17y = -3Put y = -3 in (i) , we get3x +2 (-3) =03x - 6 = 03x = 6x = 2 | |
