Answer:
y=20 + 10x
Step-by-step explanation:
Y=balance
the science cub started with 20 dollars, the first number. They gained 10 dollars a week, x, so the answer would be b.
G
Solution:
Here,
y+2x=2
y=2-2x
Now,
Putting the value of y
y+4x=0
2-2x+4x=0
2+2x=0
2(1+x)=0
1+x=0
x=-1
Then,
Putting the value of x
y=2x-2
=2×-1-2
=-2-2
=-4
Hence,the solution is (-1,-4)
