Step-by-step explanation:
<u>Step 1: Define</u>
[2 × (24 ÷ 3)] + 7
<u>Step 2: Evaluate</u>
- [Brackets] (Parenthesis) Divide: [2 × 8] + 7
- [Brackets] Multiply: 16 + 7
- Add: 23
Answer:
→ [2 × 24/3] + 7
<u>Divide 24 by 3 we get</u><u> </u><u>8</u><u> </u><u>as</u><u> </u><u>the</u><u> </u><u>product</u><u>:</u>
→ [2 × 8] + 7
<u>Now</u><u>,</u><u> </u><u>multiply</u><u> </u><u>8</u><u> </u><u>by</u><u> </u><u>2</u><u> </u><u>we</u><u> </u><u>get</u><u> </u><u>product</u><u> </u><u>as</u><u> </u><u>1</u><u>6</u><u> </u><u>:</u>
→ 16 + 7
<u>Let's add the </u><u>1</u><u>6</u><u> </u><u>and</u><u> </u><u>7</u><u> </u><u>and</u><u> </u><u>we</u><u> </u><u>get</u><u> </u><u>final</u><u> </u><u>answer</u><u> </u><u>as</u><u> </u><u>:</u>
→ 23

Substitute 1 for x in each of your equations.
f(x)=7-3x
which is
f(1)=7-3(1)
=3
Do the same for g(x)
g(x)=3x-7
which is
g(1)=3(1)-7
=-4
Then subtract g(x) from f(x):
3-(-4)
=7
