Answer:
yes
Step-by-step explanation:
(2,2)
x=2 y=2
x+y=4
2+2=4
4=4
5x+5y=20
5(2)+5(2)=20
10+10=20
20=20
The addition property of equality is used when we add 9 to both sides
6x-9 = 45
6x-9+9 = 45+9
6x = 54
The next step would be to divide both sides by 6 using the division property of equality
6x = 54
6x/6 = 54/6
x = 9
