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!

6 divided by 812 is very difficult to do without using a calculator - I would suggest the bus shelter method, as I've shown in the photo attached, but it is still quite difficult to use that method without a calculator.
<em>If</em>, however, you mean 812 divided by 6, that is a lot easier to calculate using the bus shelter method - so, just in case, I've attached the method for that too.
6 divided by 812 = 0.007389...
Answer:
