Answer:

-4.4

Step-by-step explanation:

In order to do this, we need to move the variables to one side, and the numerical values to the other.

-20-7x=-2x+2

We can do this by adding 7x to both sides first

-20=5x+2

Now we can subtract 2 from both sides.

-22=5x

Next, we can divide each side by 5.

x=-22/5

Then we simplify the fraction

x=-4.4

Answer:

x = -4.4

or

x = 22/-5

Step-by-step explanation:

-20-7x = -2x+2

-7x = -2x+20+2

2x-7x = 22

-5x = 22

x/-5 = 22/-5

x = -4.4

or

x = 22/-5
