Solve using 2) 3x-5y=15andx-2y=8

Answer 1

x - 2 y = 8 Multiply both sides by 3

3 x - 6 y = 24

3 x - 5 y = 15
-
3 x - 6 y = 24
______________

3 x - 3 x - 5 y - ( - 6 y ) = 15 - 24

0 - 5 y + 6 y = - 9

y = - 9

x - 2 y = 8

x - 2 * ( - 9 ) = 8

x + 18 = 8 Subtract 18 to both sides

x + 18 - 18 = 8 - 18

x = - 10

x = - 10 . y = - 9
