Question

Solve for x.

16 = -2x - 1

x = -8
x = -7
x = 7
x = 8

Answer 1

I tend to flip so x is on the left, so:

-2x - 1 = 16

-2x = 17

x = -17/2, which is -8.5

Rounding up, your answer would be x = -8 !

Answer 2

x = - 8.

Explanation:

Given : 16 = -2x - 1

To find : Solve for x.

Solution : We have given

16 = -2x - 1

On adding both sides by 1

16 + 1 = -2x .

17 = - 2x

On dividing both sides by -2.

x = - 8. 5

If we rounded it it would be - 8 .

Therefore, x = - 8.
