Question

Evaluate 4x-7 when x=5

Answer 1

The answer is 13.

You can evaluate this by substituting x for 5 in the expression.

4x-7
4(5)-7
20-7
13

Answer 2

Since x=5, we will make the problem into 4(5)-7. Following the order of operations, we need to multiply first. 4*5=20. Then we have 20-7, which is equal to 13. I hope this helps you!
