7x-6y=-1 5x-4y=1solving for eliminatio

Sagot :

multiply the first equation by 5 and 2nd by -7 and you get 

35x-30y=-5 
-35x+28y=-7 

now you can cancel out the x's and you get 

-2y=-12 

so 

y=6 

now you can just plug y=6 into one of the original equations and you will see that x turns out to be 5

Hope thats okay
