Hint

Reveal a hint

Solve each colored mark separately, then add them all together.

Why It Works

This is an algebra-style puzzle where colored marks hide numbers. Working out the blue mark gives 14 and the red mark gives 18. Since the question asks for the combined value, you sum every colored mark to produce 46, which becomes the final answer you must enter.

Frequently asked questions

What is the answer to Brain Test 5 Level 67?

Find that the blue question mark is 14 and the red one is 18, then add 14 + 14 + 18 to enter 46.

How do I solve the blue question mark in Brain Test 5 Level 67?

Balance the first equation to work out that the blue symbol equals 14 and enter that value.

Why is the red question mark 18?

Solving the second equation on its own gives the red symbol a value of 18.

Add the two blue marks (14 and 14) plus the single red mark (18) to reach the total of 46.

Is there a video walkthrough for Brain Test 5 Level 67?

Yes, the video solves each colored mark first and then sums them up to enter 46.

Why do I add the marks only at the end?

The last scene asks for the total of every colored symbol, so you must sum them after solving each one separately.
