Answer :
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]
