Hi.
STEP 1:
Let's start by assigning letters to stand for each player.
J = Jackson
L = Leslie
STEP 2:
The problem tells us that Jackson scored 43 more points than Leslie. We want to express this mathematically:
J = L + 43
STEP 3:
We know that the sum of the points scored by the players is 1,165. Again, we want to express this mathematically:
J + L = 1,165
STEP 4:
Since we know that J = L + 43, let's substitute that for J in the equation used in step 3.
(L + 43) + L = 1,165
STEP 5:
Simplify by adding like terms on the left side of the equation together.
2L + 43 = 1,165
STEP 6:
Get the term containing L alone by subtracting 43 from both sides of the equation.
2L = 1,122
STEP 7:
Divide 2L by 2 so that L is alone. Be sure you also divide 1,122 by 2.
L = 561
So Leslie scored 561 points. Since Jackson scored 43 more points than Leslie, she scored 561 + 43 = 604 points.
STEP 8:
Finally, we want to double-check our answers. Does the number of points each player scored add up to 1,165?
561 + 604 = 1,165
We have the right answers!
