Question

If ×=10 what is the value of 2×+5

Answer 1

In order to calculate the value of 2x + 5 if x=10, we would need to substitute in the expression 2x + 5 the variable x with the number 10.

Therefore, 2x + 5 if x=10 would be equal to:

2(10)+5=20+5=25

Therefore, the value of 2×+5​ if x=10 would be 25
