Pretty sure it's 0, if you mean 2 to the power of 0
As we know y=3/4x-3
Let's put it in the second equation
3/4x-3=1/4x+1
3/4 x -1/4 x = 1+3
2/4 x = 4
X= 4*4/2
x=8
Put x= 8 in first equation
y= 3/4 *8 -3
y=6-3
y=3
Check the answer
3=3/4 *8 -3
3=6-3
3=3
Correct
So(y, x) = (3,8)
Because x=8 and y=3
Well i don’t understand your question but the pattern is infinitely (+2) the next 3 terms are 19,21,23
I do not see any illustrations, but repeated subtraction is the exact same as division.
I hope this answer was useful, and as always, I am joyous to assist anyone at any time.
