Answer:
If x = 5, then 3x + 4x - 15 equals 20
Step-by-step explanation:
Here, we are given the value of x, which is 5.
1. Substitute 5 as the value of x in the equation:
3x + 4x - 15 = ?
3(5) + 4(5) - 15 = ?
15 + 20 - 15 = ?
2. Simplify:
15 + 20 - 15 = ?
35 - 15 = ?
20 = ?
3. Check your work:
3x + 4x - 15 = 20
3(5) + 4(5) - 15 = 20
15 + 20 - 15 = 20
20 = 20 ✅
Therefore, if x = 5, then 3x + 4x - 15 equals 20
