<span>t's call P the number of art brushes that Monique has.
Chelsea has 11xP (that is 11 times as many as Monique)
Together they have:
P + 11xP = 12xP
That means 12xP = 60 (60 is the number of art brushes they have together)
In order to find how much is P, we need to divide:
60 Ă· 12 = 5 brushes
P = 5 ; that means has Monique 5 art brushes.
Chelsea has 11 times as many art brushes as Monique:
11 x 5 = 55 brushes</span>
Answer:
Step-by-step explanation:
Given the simultaneous equation
3x+4y=15. Equation 1
3x-y=30. Equation 2
Using elimination method
Sutract equation 2 from 1
Then, will have
3x-3x+4y--y=15-50. -×-=+
4y+y=-15
5y=-15
Divide Both sides by 5
y=-15/5
y=-3
From equation 2
3x-y=30
3x--3=30
3x+3=30
3x=30-3
3x=27
Divide both side by 3
x=27/3
x=9
Then, x=9 and y=-3
