to solve the equation:-3×5-6y=1we need to simplify the left side of the equation first by multiplying -3 with 5 which gives us -15. then, we can write the equation as:-15-6y = 1next, we will isolate the term containing y by adding 15 to both sides of the equation:-15 + 15 - 6y = 1 + 15simplifying the terms on the left side:-6y = 16finally, we isolate the variable y by dividing both sides of the equation by -6:-6y/(-6) = 16/(-6)y = -8/3
