Given :
Two equations :
-8x + 3y = -17 ....1)
3x - y = 7 ....2)
To Find :
The solution of the system.
Solution :
Multiplying equation 2) by 3 and adding with equation 1), we get :
(-8x + 3y) + 3(3x - y) = -17 + 21
x = 4
Putting above value of x equation 2) we get :
12 - y = 7
y = 5
Therefore, solution of system is ( 4,5 ).
Answer:
-7
Step-by-step explanation:
2-3(3)=-7
P = $2000
R = 5.4%
T = 2 yrs
Interest = PTR/100 = 2000*2*5.4/100 = $216
Balance = $2000 + $216 = $2216
The answer is B.12 because if she make 3 in 5 hours that means that in twenty hours should make 12 because it's like this 3 x 4 = 12 and 5 x 4 = 20 so when you add the hours up you'll get the answer
3a^6 -2a^5 +a^4
Brainly says my answer is too short so I have to add extra text here
