Match each equation to equivalent equation. -4x+3y=20 -6x-2y=10. 2x +5y=18 4X +10 Y equals 36
12 X minus 9Y equals -60
-24X minus 8Y equals 40

4x + 10y = 36  ≡  to 2x + 5y = 18

As you can see, the the coefficients on the first one are double those in the second.

12x - 9y = -60  ≡  to -4x + 3y = 20

In this case, the terms in the first one are all the same, but multiplied by -3

And by simple elimination we can say:

-24x - 8y = 40 ≡ -6x - 2y = 10

In this case, the terms of the first equation are equal to those of the latter, but all multiplied by 4.
