Answer:
3
Step-by-step explanation:
a = 3
multiply 2 and 3
2 * 3 = 6
simplify
18/6 = 3
I think its 8? someone correct me if im wrong.
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.
