In a video game, Bob can score 3 points (x) or 4 points (y) by hitting targets. To win the game he must score at least 20 points

MariettaO [177]

Well,

we know that we need to accumulate points from x and y to reach 20 points.

since x provide 3 and y provide 4 points, the formula would be :

3x + 4y = 20
