Step-by-step explanation:
<u>Step 1: Define</u>
14.9 + 1/3(-12 - 27x) - 33.2
x = -3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: 14.9 + 1/3(-12 - 27(-3)) - 33.2
- Multiply: 14.9 + 1/3(-12 + 81) - 33.2
- Add: 14.9 + 1/3(69) - 33.2
- Multiply: 14.9 + 23 - 33.2
- Add: 37.9 - 33.2
- Subtract: 4.7
<span>y = 3x - 4
x = 9
then
</span>y = 3x - 4
y = 3(9) - 4
y = 27 - 4
y = 23
solution (9, 23)
answer
<span>D. (9, 23)</span>
