Question

When subtracting 12 from three times the sum of 8 and a number, you get half of that number. Write and solve the equation for this sentence.

Answer 1

equation: 3(8 + x) - 12 = 1/2 x

answer: -4.8

Explanation:

3(8 + x) - 12 = 1/2 x

24 + 3x - 12 = 1/2 x

12 + 3x = 1/2 x

12 = - 2 1/2 x

- 4.8 = x
