Best ResponseYou've already chosen the best response.0First thing is that you must get rid of one of the variables. you do this by looking at the 2 equations to see which one is easier to cancel. so look at y terms  what can you multiply the 1st equation to cancel out y terms

Best ResponseYou've already chosen the best response.0We have to eliminate y. So What would you be multiplying both the equation with so then you can add or subtract to eliminate y and get x.

Best ResponseYou've already chosen the best response.02x + 5y = 13 .............(1) 3x  4y = 8 ................(2) If you multiply both sides of equation (1) by 3, and you multiply both sides of equation (2) by 3 then the coefficient of x will be 6 in both the resulting equations. Then we can take the next step to eliminate x. Can you do the first step?
