5x - 3x + 4 = -4 +20
2x + 4 + 16
subtract 4 from each side
2x=12
divide each side by 2
x=6
Answer:
The terms are like.
Step-by-step explanation:
Like terms are terms whose variables and, if applicable, powers are the same. It doesn't matter if the coefficients are the same or not.
Since the terms have the same variable 'x', they are all like terms.

Answer:
3.7
Step-by-step explanation:
Inversely means we are taking the constant and dividing it.
So y varies inversely with x means "y=k/x".
k is a constant. We can find the constant if they give us a point on this curve.
The constant is a number that doesn't change no matter your input and output.
So they actually give us k=8.88 and y=2.4 so let's input this:

We need to solve this equation for x. You can do your favorite thing in cross-multiply. But how, Freckles? Well just slap a 1 underneath that 2.4. You can do that because 2.4/1 is still 2.4.

Cross-multiply:


Divide both sides by 2.4:
