Answer:

Xavier has 5 dollars

Step-by-step explanation:

2x represents how much money Alex had, the -3 is how much he spent, and the 7 is how much he has now

[tex]2x-3=7[/tex]

Add 3 to both sides

[tex]2x=10[/tex]

divide both sides by 2

[tex]x=5[/tex]

Checking my work:

[tex]2*5-3=7\\10-3=7\\7=7[/tex]
