1 answer:
yan [13]3 years ago
8 0

Answer:

We first must solve for x

9x-x+5x=260\\13x=260\\x=30

When we have x, we put it in to the second equation

Bx=200\\\\B=\frac{200}{x} \\\\B=\frac{200}{30}\\\\B=\frac{20}{3}

How do you factor the common factor out of 30x^2-12x
Anika [276]
The answer would be 6x(5x-2).

Since both terms have x in them, x will be apart of your answer.

The GCF of 12 and 30 is 6.

So you can factor out 6x from both terms.

Hope this helps!
