For this case we have the following equation:

We must replace the following value in the equation:

Substituting we have:

Simplifying the given expression we have:

Then, using logarithm properties in base 10, we can rewrite the expression:

Finally, making the product, the result is:
Answer:
option 4
35x -10y=-120
10x +10y= 30
45x=-90
x=-2
5(-2)+5y=15
-10+5y=15
5y=25
y=5
