Multi-Step Equation
Jimena scores 12 goals every half a game she plays, at this game she scored all 12 goals in 5 minutes In her second half of the game she scored 18 goals plus she did it in 5 minutes. If she averaged it out how many goal did she make per minute.
12 + 5x = 18 + 5x
12 + 18 = 30
5x + 5x = 10x
30 = 10x
x = 3
