Answer:
A. x=2, y = 7.
B. (2, 7).
Step-by-step explanation:
A. You can eliminate y by subtracting the equations:
y = 8x - 9
y = 4x - 1 Subtract:
0 = 4x - 8
4x = 8
x = 8/4 = 2.
Now substitute for x in the first equation:
y = 8(2) - 9 = 7.
Check in the second equation:
y = 4x - 1
7 = 4(2) - 1 = 7. Check is OK.
B. On the graph they will intersect at the point (2, 7).
They will intersect here because the values x=2 and y=7 satisfy both the 2 equations.

-2x-2
-2(x+1)
Okay, so his remaining money would have been 20.00 if he spent half of it (10.00) on his lunch. If one third of his money was 20.00, we need to add two thirds more to create the whole amount. 20 + 20 + 20 = 60.00.
At first, he had 60.00
