Answer:
x = x
True
Step-by-step explanation:
First, distribute the -7 by multiplying it by everything inside of the parenthesis.
-7 * x = -7x
-7 * -4 = 28
Now, put it together.
-7x + 28 = -7x + 28
We can already tell the the statement is x = x, which is true, but let's solve it just to make sure.
Isolate the x.
Subtract 28 from each side.
-7x + 28 = -7x + 28
-28 -28
Simplify it.
Divide each side by -7.
-7x = -7x
----- -----
-7 -7
x = x
This is true
