Write the 2 equations:

5x-2y=18
-5x+3y=-22

You can see that the coefficients of x are opposites, so you can add them(the 2 equations) to eliminate x.

Adding them, you get:

y=-3

So now that you know y, you can substitute the value of y into one of the original equations. Let's substitute it in the first one:

5x+6=18

Solving this, we get:

5x=12
x=12/5

x=12/5, y=-3

Alina [70]
There are a total of 20 hamsters. I solved it by dividing the 8 hamster by 2 to get what 1/5 would be. After i know 1/5=4 hamsters i multiplied 4*5

4 hamsters is the same as 1/4 of all the hamster

8 hamsters=2/5

12 hamster=3/5

16 hamster=4/5

You can use Desmos to graph these and make your own judgment as to the intercepts and rates of increase/decrease.

The ones with a base < 1 will decrease rapidly, then slowly. The one with a base > 1 will increase slowly, then rapidly. The y-intercept is the multiplier in front of the base.
