Answer:
(3,0.5)
Step-by-step explanation:
The given system has equations:

Let us multiply the second equation by 4 and the first equation by 10.

We add both new equations to get:

Put x=3 into the first equation and solve for y.

The point of intersection is the solution to the system of equation which is (3,0.5)
Hey! I'll provide you the answers!
First you want to simplify the equation using cross-multiplication.

Finally, you would want to divide both sides by 15.
n = 161
The first question’s answer is the last option. And the range is 104
Answer:
