Answer:

7.22 x 10^5

Step-by-step explanation:

Remember that the decimal is always to the right of the ones place.

1. Move it one place to the left and multiply by 10 to compensate.

2. Move it two places to left and multiply by 10^2.

3. Move the decimal point three times and multiply 10^3 to compensate, and the pattern continues until you reach the very last digit, the 7.

4. Numbers after the 7 that are not zeros will be after the decimal point.

so, 7.22 x 10^5

A product means multiplication, so...

(x * -2) +8 = -4
-2x + 8 = -4

To isolate the x, we have a couple of different ways, but the easier for now would be to start off by moving the 8 to the other side via subtracting both sides by 8:
-2x + 8 - 8 = -4 - 8
-2x = -12

Next, we divide both sides by -2
-2x / -2 = -12 / -2
x = 6
