Answer:
a=2 , b= (-1)
Step-by-step explanation:
8a-4b=20/×(-2)
5a-8b=62
-16a+8b= -40
5a-8b=62
now -8+8=0 right? so the only parameter that we have is a.
-16a+5a= -40+62
11a = 22/(÷11)
a=2
in order to find b, we will replace a with its value in one of the original equations (it doesn't matter which one you will choose).For instance, I chose the first one.
8×2-4b=20
-4b=20-16
-4b=4/÷(-4)
b= -1
The number would be 826. 826 rounded to the nearest ten would be 830 because when you have a number at the end that is 5 or higher, it would round up.
