For this case we have to:
x: Variable that represents the points scored by Bev
y: Variable that represents the points scored by Ike
According to the data we have:
[tex]x = 540\\x = y + 158[/tex]
We substitute the first equation in the second one:
[tex]540 = y + 158[/tex]
We clear the variable "y":
[tex]y = 540-158\\y = 382[/tex]
So, Ike scored 382 points.
Answer:
Ike scored 382 points.
