Answer:
-6
x - 6 is the equation, (unless there was a y, and it pasted wrong)
Explanation:
You do additive property of equality by adding 1 to both sides.
-6x - 1 = 35
= -6x - 1 + 1 = 35 + 1
= -6x = 36
Division property of equality by dividing both sides by -6 or 6
= -6/-6x = 36/-6
= 1x = -6
x = -6
