Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
9x - 5y = -9
(a - 1, 9)
<u>Step 2: Solve for </u><em><u>a</u></em>
- Substitute in coordinate [Equation]: 9(a - 1) - 5(9) = -9
- Evaluate [Order of Operations]: 9(a - 1) - 45 = -9
- [Addition Property of Equality] Add 45 on both sides: 9(a - 1) = 36
- [Division Property of Equality] Divide 9 on both sides: a - 1 = 4
- [Addition Property of Equality] Add 1 on both sides: a = 5

I think you're asking for what the x value is??
to find this you have to have the variable(s) in this case, x, on one side of the equation.
you need to combine like terms and also subtract 8.
2x+8-22x=-2
-8
2x-22x=-10
Combine like terms:
-20x=-10
Now divide by -20:
x=1/2
Your solution is:
x=1/2
