In a recent basketball game Dwayne scored 22 points. He made four times as many two point baskets as he did three point baskets. If all of his points were on two and three point baskets, how many three point baskets did he make?
If we set the number of three point baskets he made as x, we can write the following equation for the total amount of points he scored.
22 = 2 * (4x) + 3 * x
22 = 8x + 3x
22 = 11x
2 = x
x = 2
Since x = 2, we know he scored 2 three pointers.
I hope this helped,
