Lee scored 25 points in yesterday's game. That has 3 more than twice the number of points Alex scored.Which equation can be used to find, a, the number of points Alex scored?
Lee scored 3 more than twice the number of points Alex scored
That is, Lee scored 3+ twice the number of points Alex scored
Lee scored=3+2*Number of points Alex scored
Lee scored=3+2*a
Whereas, Lee scored=25
So, we have,
25=3+2*a
Answer: Option (D)
25=3+2a
To solve for a, Let us subtract 3 from both sides
25-3=3-3+2a
22=2a
Let us divide by 2 on both sides
2a/2=22/2
a=11
