Answer:
No solution
Step-by-step explanation:
Note how "2x" shows up in both equations. This suggests doing a substitution to solve the system.
Focus first on the first equation. Solving 2x - y = 7 for 2x, we get:
2x = y + 7.
Next, we substitute y + 7 for 2x in the second equation:
y = (y + 7) + 3.
Simplifying this produces:
0 = 10
This is not true and can never be true. Thus, this system has no solution.
The correct answer is D. 36 x 1/9
When there is a negative exponent on a whole number:
4 ^-2
1/ 4 ^2 = 1b16

Answer:
4 times larger
Step-by-step explanation:
Answer:
We have:
7 + 4 = 11;
11 - 7 = 4;
11 x 2 = 22;
4 x 4 = 16;
22 - 16 = 6;
Finally, 8 x 6 = 48;
