Question

Twice the difference of a number and 2 is equal to three times the sum of the number and 9. Find the number

Answer 1

The value of x is equal to -31.

2(x - 2) = 3(x + 9)

Distributive property.

2x - 4 = 3x + 27

Subtract 2x from both sides.

-4 = x + 27

Subtract 27 from both sides.

-31 = x
