Question

2x – 3 + 5 if x = 2 please show your work

Answer 1

Answer:

6 is your answer.

Step-by-step explanation:

Note that: x = 2

Plug in 2 for x in the expression given:

2x - 3 + 5 = 2(2) - 3 + 5

Remember to follow PEMDAS as well as the left -> right rule. First, multiply, then subtract, and finally add:

2(2) - 3 + 5 = (2 * 2) - 3 + 5 = 4 - 3 + 5 = 1 + 5 = 6

6 is your answer.

4-3+5

Then do -3+5

-3+5= 2

4+2
