While working on an assignment, Jose solved an equation with the following steps: 4x - 2(3x + 1) = -5
Step 1: 4x - 6x + 1 = -5
Step 2: -2x + 1 = -5
Step 3: -2x = -6
Step 4: x = 3
When Jose checked his answer, it was incorrect. In which step did Jose make his
mistake?

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
