Four times the sum of twice a number and 6 is -8. Find the number.

Hey there! :)

x = -4.

Step-by-step explanation:

We can write an algebraic equation to express this situation.

Let 'x' represent a number:

4(2x + 6) = -8.

Begin by dividing both sides by 4:

2x + 6 = -2

Subtract 6 from both sides:

2x + 6 - 6 = -2 - 6

2x = -8

Divide 2 from both sides:

2x/2 = -8/2

x = -4.
