Question

Which equation can be used to find the solution of (12)2x=32 ?



−12x=5

−2x=5

12x=5

2x = 5

Answer 1

(12)2x=32 can be rewritten as 24x=32
divide both sides by 8. The result is 3x=4

Therefore none of the equations are correct.

Answer 2

If the 12 is really 1/2 then the answer is -2x=5. I know this for sure because i just took the test and got it correct.
