(f+g)(x) is 3x^2 + 3x/2 - 9
(f+g)(x)=f(x)+g(x)=x/2-3+3x^2+x-6= 3x^2 + 3x/2- 9

Step-by-step explanation:
<u>Step 1: Define</u>
5(w + 2.2) - 4w = 9.3
<u>Step 2: Solve for </u><em><u>w</u></em>
- Distribute 5: 5w + 11 - 4w = 9.3
- Combine like terms: w + 11 = 9.3
- Isolate <em>w</em>: w = -1.7
<u>Step 3: Check</u>
<em>Plug in w into the original equation to verify it's a solution.</em>
- Substitute in <em>w</em>: 5(-1.7 + 2.2) - 4(-1.7) = 9.3
- (Parenthesis) Add: 5(0.5) - 4(-1.7) = 9.3
- Multiplication: 2.5 + 6.8 = 9.3
- Addition: 9.3 = 9.3
Here we see that 9.3 does indeed equal 9.3.
∴ w = -1.7 is the solution to the equation.
