Answer:
y = 20 - x
Step-by-step explanation:
Perimeter of a rectangle = 40 units
2 * ( length + width) = 40
2* (x + y) = 40 {Divide both sides by 2}}
x + y = 40/2
x + y = 20 {Subtract x from both sides}
y = 20 - x
Answer:
30 goals last season
Step-by-step explanation:
Goals this season = 8
Goals this season = 1/3 of goals last season - 2
Let Goals scored last season = x
Therefore,
8 = 1/3x - 2
8 = x/3 - 2
8 + 2 = x / 3
10 = x / 3
x = 10 * 3
x = 30
