Question

What is the value of x in the equation - 2/3x + 9 = 4/3x - 3?

Answer 1

18

Explanation:

2/3x + 9 = 4/3x - 3 (given)

2/3 (18) + 9 = 4/3 (18) - 3 (substitute for x)

12 + 9 = 24 - 3 (simplify)

21 = 21 (answer)

18 is correct

Answer 2

=) -2/3x - 4/3x = - 3 - 9

=) - 6/3x = - 12

=) -2x = -12

=) x = -12 / -2

=) x = 6
