use either substitution or elimination to solve
8x+15y=13
2x5y=1

victoria,
Multiply the 2nd equation by 3 and you'll get 6x  15y = 3 "Add" this equation to the 1st equation and you eliminate the y variable and get 14x = 10.Therefore, x = 5/7. Substitute this into one of the original equations and solve for y.
