<u>Step 1: Define</u>
f(x) = -2x + 3
g(x) = 2x + 3
f(3) is x = 3 for function f(x)
g(7) is x = 7 for function g(x)
<u>Step 2: Solve</u>
- Substitute in <em>x</em> [Functions]: f(3) = -2(3) + 3, g(7) = 2(7) + 3
- Substitute in functions: f(3) + g(7) = -2(3) + 3 + 2(7) + 3
- Multiply: f(3) + g(7) = -6 + 3 + 14 + 3
- Add: f(3) + g(7) = -3 + 14 + 3
- Add: f(3) + g(7) = 14
