4n-3=5 add 3 both sides 4n=8 divide by 4 both sides n=2

7n + 2 = 4n + 17Subtract 2 from each side:7n = 4n + 15Subtract 4n from each side:3n = 15Divide each side by 3:n = 5
Follow these steps 1. Using distributive property, first, distribute 36 into 4n and 45 so : 36x4n - 36x5 that becomes (144n-180)45 2. Distribute 45 to 144n and 180 so: 45x144n- 45x180 that becomes 6480n-8100 3. SImply by dividing by 1620 4n-5 so your final answer is 4n-5
4n + 5
n = 1 7n + 6n - 5 = 4n + 4 13n - 5 = 4n + 4 13n - 4n - 5 = 4n - 4n + 4 9n - 5 = 4 9n -5 + 5 = 4 + 5 9n = 9 n = 1
4n-3=5 add 3 both sides 4n=8 divide by 4 both sides n=2
If both dogs pull the rope with a force of 85N each in opposite directions, the rope will experience a tension of 85N as well. Since the forces are equal and opposite, the rope will not move in either direction.

It is 4n-13 and so the next number will be 11
