Question 466226: Solve the system by the elimination method.
5x+5y= -13
7x-2y=11
Answer by Love math(28) (Show Source): You can put this solution on YOUR website!
5x+5y= -13.......Time(2).. 10x+10y=-26
7x-2y=11.........time(5)....35x-10y=55
..................Add..........45x = 29
................................x = 29/45
substitution: x = 29/45 find y
5(29/45)+5y= -13
145/45+5y = -13
.........5y= -13-(145/45)
..........y=(-730/45)/5
..........y= -730/(45*5)
..........y=-730/225
..........y = - 146/45
