4x-6y=2 3x+5y=11 jonas used the linear combination method to solve the equation shown. he multiplied the first equation by 3, and the second equation by another number to eliminate the x terms. what number did jonas multiply the second equation by?

First equation by 3
4x-6y=2
times 3
12x-18y=6
ok so see which terms can cancel and are factors

3x+5y=11
3 times what whole number=-12 answer is -4 so this is it

5 times what whole number=18 (so it can cancel) answe ris nothing so this isn't it

multiply second equaton by -4 to make 3x into -12x to add tothe 12 x in the other equation to gget 0x

answer is -4

The best estimate would be about 1 foot
