3(b+f) you just do the sum and times it by 3
We start with:
y=2x-15
y=5x
Now, we have a perfectly set-up variable we can get rid of: <em>y.</em>
But we need to make either the top or bottom equation negative, so for simplicity, let's make the bottom one negative.
y=2x-15
(-y)=(-5x)
Now simplify.
-3x-15=0
Add 3x on both sides.
3x=15
Divide by 3 on both sides.
x=5
Hi,
The greatest common factor of 30 and 50 is 10.
Have a great day!
Yes. When solving a problem like this, multiply the base numbers normally, and add the exponents together.
