Question

Leandre scored 10 points less than 3 times the number of points that Rayanna scored. Leandre scored 11 points. How many points did Rayanna score?

Answer 1

Note that:

• L = 3r - 10
• L = 11

Substitute the value of L into the equation to find r.

• L = 3r - 10
• => 11 + 10 = 3r
• => 21 = 3r
• => r = 7

Rayanna scored 7 points.

Answer 2

7 points

Explanation:

Let n represent the points Rayanna score.

We can use this to set up an equation:

11=3n-10

Add 10 to both sides:

21=3n

Divide both sides by 3

n=7

Therefore Rayanna scored 7 points
