n/6=7
n=42
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.

Answer: the fraction 1/9</h3>
It is approximately equal to 0.1111
=================================
To get this answer, we use the rule

The negative exponent tells us to apply the reciprocal to get the exponent to be positive.
So,

Squaring -3 means you square the negative as well
