Answer:
No, it is not a solution
Step-by-step explanation:
First let's simplify 2x - 5 = 3
2x - 5 = 3 (add 5 to both sides)
2x - 5 + 5 = 3 + 5
2x = 8 (divide both sides by 8)
2x ÷ 2 = 8 ÷ 2
x = 4
As you can see, 7 is not a solution for 2x - 5 = 3
We can double check by substituting 7 for x:
2(7) - 5 = 3
14 - 5 = 3
9 ≠ 3
