1. Jackson has $1.50 in quarters and dimes. Let x represent the number of quarters
and y represent the number of dints. Find the domain and range of this situation.

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
