3x+9y=-9
-3x+8y=26
solve each system by elimination

x = -6

y = 1

Explanation:

Elimination is a process in solving the system of the two unknowns.

It consists of subtracting or adding two equations in order to cancel out one of the unknowns.

In this case:

3x + 9y = -9

-3x + 8y = 26

we see that we can eliminate 3x and -3x by adding them up. 3x and -3x will cancel each other out and give 0 so we will be left with only y.

So, when we add them up, we get:

3x + 9y + (-3x) + 8y = -9 + 26

17y = 17

y = 1

Now that we know the value of y, we can plug it back into any of the two equations to find x:

3x + 9y = -9

3x + 9 = -9

3x = -18

x = -6

the noble might have thought that the system was far because they had lot of things and riches and the serf would have thought that the feudal system was un fair because of the way they were treated.
