We can only use two at a time for the time being.

-6a - 1 ≥ 3a - 10

add 10

-6a + 9 ≥ 3a

add 6a

9 > 9a

divide

1 ≥ a

Now we know a is less than 1 and can fill all a's with 1 in order to find the value of z.

-2z + 3 ≥ 6 * 1 - 1

add 1

-2z + 4 ≥ 6

Subtract 4

-2z ≥ 2

Divide by -2

z ≥ 1

z is ≥ 1, and a is ≤ 1
