Question

Four more than twice a number is -10. Find the number.

Answer 1

-7

Explanation:

Four more than twice a number is -10.

Let the number be X,

2x + 4 = -10

2x = -10 - 4

2x = -14

x = -14/2

x = -7

Answer 2

2n + 4 < -18

subtract 4 from both sides:

2n < -22

Now, divide both sides by 2:

n < -11

The solution is n < -11
