8x+5y=-133x+4y=10what is the x and y using elimination?

Multiply both equations by appropriate constants to get the coefficients of either or in both equations to be the same. One choice would be to multiply the first equation by 3 and the second by 8:

Then subtract either equation from the other to eliminate . I'll take the first from the second:

Then solve for in either equation. From the second one, we find

So the solution to this system is the coordinate pair (-6, 7).

entering that problem on the tube might get you an answer

the answer is y = 11.54

hope this : )
