Question

Diego scored 9 points less than Andre in the basketball game. Noah scored twice as many points as Diego. If Noah scored 10 points, how many points did Andre score?

Answer 1

Let andre score be x points.

then Diego's score will be (x-9) points.

Noah's points=2(x-9) points

the equation is 2(x-9) = 10

dividing both sides by 2,

• 2(x-9)/2 =. 10/2
• x-9= 5

adding 9 both sides,

x-9+9= 5+9

• x=14.
