In order to find out what the blank of your expression is,, we must solve for y. We can start doing this by distributing -2 through the parenthesis. y - 4 = -2x - 6 Now you need to move the constant to the right side and change its sign. y = -2x - 6 + 4 Calculate the sum of -6 + 4. y = -2x - 2 Since we cannot simplify this down any further,, y is going to equal -2x - 2. Let me know if you have any further questions. :)
