Answer:
x=3
Step-by-step explanation:
7(x - 7) = -28
x - 7 = -4
x = 3
Answer:
x = 3
Step-by-step explanation:
Your goal is to isolate the x from the other numbers.
-28 = 7(x - 7)
Distribute the 7 to the (x - 7)
You will end up with:
-28 = 7x - 49
Add 49 to both sides of the equation to further isolate the x
21 = 7x
Finally, divide both sides by 7 so x is by itself
x = 3
