Answer:
Left page: 189, right page: 190
Step-by-step explanation:
When you put left page as x, the other page is x+1 because left and right page numbers are not the same but difference of 1.
With these information, you can make equation
[tex]x+x+1=379[/tex]
Add two x together.
[tex]2x+1=379[/tex]
Subtract 1 for each side.
[tex]2x=378[/tex]
Divide 2 for each side.
[tex]x=189[/tex]
So, x was left page but right page was x+1.
Left page is 189 and right page is 189+1, 190.
