Can someone help me with this geometry question I don’t understand it
1 answer:
When answering questions like these, it helps to draw arrows,, the variable will always be on top, so in this situation you would draw an arrow from the a to the 10 and an arrow from the 38 to the 12 making them both fractions, you would then cross multiply, after cross multiplying you would get 12a=380 then you would divide by 12 equaling 31.6

The answer is B.
We can prove this by putting -1/3 into x.
6(-1/3) - 5 = 7
Multiply -1/3 by 6.
-2 - 5 = 7
Subtract 5 from -2.
-7
7
So, -1/3 is not a solution to this equation.
Hope this helps!
