Answer:

The second camera. The second camera is $30 cheaper than the first camera.

Step-by-step explanation:

The equation of the first store is y = 20x + 50. Keep this in mind.

Replace x with 12 in each of these equations to determine which is cheaper.

y = 20(12) + 50 = $290

y = 15(12) + 80 = $260

So the second store is cheaper.

Answer:

x = 2

Step-by-step explanation:

First, let's write out our equation:

2x-4=6-3x

I want to isolate x on one side, so first, I'll add 4 to both sides to remove the -4 from next to 2x:

2x-4+4=6-3x+4\\2x=-3x + 10

Notice that I combined like terms with the -4 and 4 (to get 0) and the 6 and 4 on the right side (to get 10). Next, I'll add 3x to both sides:

2x + 3x = -3x + 3x + 10

And then I'll add like terms:

5x=10

Now, all we have to do is divide both sides by 5:

5x/5=10/5\\x=2

And there's our answer. Hopefully that's helpful! :)
