Answer:
The value of x is (-4) and y is (-5)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
<h3><u>To Find</u>;</h3>
Now,
-6x = 24
-6x/(-6) = 24/(-6)
x = -4
So, Substitute the value of x in x – 5y = 21
x – 5y = 21
-4 – 5y = 21
-4 + 4 – 5y = 21 + 4
-5y = 25/
-5y/(-5) = 25/(-5)
y = -5
Thus, The value of x is (-4) and y is (-5)
<h3>
<u>For </u><u>Verification</u>;</h3>
x – 5y = 21
-4 – 5(-5) = 21
-4 + 25 = 21
21 = 21
-6x = 24
-6(-4) = 24
24 = 24
L.H.S = R.H.S
Hence Verified!

Answer:
it would be 3 days and 54
Step-by-step explanation:
s^3 power is 27, 4(3)+15 is 27, 27+27 equals 54
Answer:y=-1/2
Step-by-step explanation:
125=(1/25)^(y-1)
5^3=(5^(-2))^(y-1)
5^3=5^(-2(y-1))
The same base eliminate each other we then have
3=-2(y-1)
3=-2y+2
Collect like terms
2y=2-3
2y=-1
Divide both sides by 2
2y/2=-1/2
y=-1/2
