Question

Twice a number is equal to negative four. Which equation could be used to find the number?

Answer 1

2x = -4

Explanation:

x is 'a number'

If you wanted to solve your equation:

2x = -4

2x/2 = -4/2 Divide both sides by 2

(To get x alone)

x=-2

Answer 2

2n = - 4

n = - 4 : 2

n = - 2
