Answer 3

If there's an 'x' sitting outside or out front of the left matrix, then this is telling you to multiply every element in the left matrix by x.


So 5x = -35, which means that x = -7


This means that you're multiplying every element in the left matrix by -7 to get corresponding elements in the right matrix.
