Hello,
Answer B
2x+y=6 (1)
-4x+3y=8 (2)
2*(1)+(2)==>5y=20==>y=4
==>2x=6-4==>2x=2==>x=1

Step-by-step explanation:
I believe it is 1.625
( 2^2 + b^2 = 5^2 )
Answer:
8 is 73 corresponding and 9 is 107 supplementary
Step-by-step explanation:
First, you must distribute the negative sign(otherwise considered a negative one). This gives you x - 4x + 7 = 5x - x - 21.
Then, simplify any like terms you can: -3x + 7 = 4x - 21.
Simplify this even further: 28 = 7x
The final answer is x = 4
