Answer:
x=8 y=2
Step-by-step explanation:
solve for x
1. 4x+4y=40
2. subtract 4y from both sides
3. 4x=40-4y
4. divide both sides by 40
5. [tex]\frac{4x}{4} = \frac{40-4y}{4}[/tex]
6. dividing by four undoes the multiplication by four
7. [tex]x=\frac{40-4y}{4}[/tex]
8. divide 40 - 4y by 4
9. x=10-y
10. use the last equation to solve the rest
