To eliminate one of the variables, make one of equations have equal variables just negative and positive. To do this, multiply the second equation by 3 to get y to 3y, but you must multiply the whole equation. 15x3y=57 2x+3y=6

Add the equations together now! 15x+2x=17x 57+6=51 17x=51 x=3

When u multiply the second equation by 2 u get 10x2y=38. Let us name that as equation (3). The resultant equation u get by multiplying the first equation by 5 is 10x+15y=30. Let us name this equation(4). Subtracting (3) from (4) (4)(30=> 10x+15y10x+2y=30(38) 17y=68 y=68/17 y=4
