Step-by-step explanation:
<u>Step 1: Define</u>
-4x + 3y = -2
y = x - 1
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: -4x + 3(x - 1) = -2
- [Distributive Property] Distribute 3: -4x + 3x - 3 = -2
- Combine like terms: -x - 3 = -2
- [Addition Property of Equality] Add 3 on both sides: -x = 1
- [Division Property of Equality] Divide -1 on both sides: x = -1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em> [Original Equation]: y = -1 - 1
- Subtract: y = -2

Answer:
I'm most certain it is 8.89
Step-by-step explanation:
the formula:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((49.000 - 45.000) / 45.000) * 100 = 8.89 %
