Answer:
(-2, -4)
Step-by-step explanation:
–2x + 2y = -4
3х + Зу = -18
Divide the first equation by 2
–2x/2 + 2y/2 = -4/2
-x +y = -2
Divide the second equation by 3
3х/3 + Зу/3 = -18/3
x + y = -6
Add these equation together
-x +y = -2
x + y = -6
-------------------
0x + 2y = -8
2y = -8
Divide each side by 2
2y/2 = -8/2
y = -4
Now we need x
x+y = -6
x-4 = -6
Add 4 to each side
x-4+4 = -6+4
x = -2
Answer:
The interest earned the following year = $75
Step-by-step explanation:
Interest = $75
Rate = 4%
Time = 1 year
To find the Principal, Using the formula for Simple Interest :
Now, to find amount of interest for the second year :
T = 2 years
t = 1 year
Principal = $1875
Rate = 4%
Hence, The interest earned the following year = $75
Multiply 2x-8y=10 by 3 and that should eliminate the X's
