2 N cubed (3)

Whatever your value of n is, you need to multiply it by 5 and then add 2 to get your answer. Below is how to solve it algebraically: 5n+2 = 0 (it needs to be equal to something in order to solve it, so I assumed that it equals zero) 5n = -2 n = -2/5
n=3,y=4 2(n+3y)=30
You can either do this by trial-and error, or solve the equation n + (n + 2) + (n + 4) = 48.
n = 8 Solution Steps Step 1 Multiply on both sides 1/4 n * 4 = 2 * 4 Step 2 Simplify the left side n = 2 * 4 Solution n = 8
(n+4)2 = 36 This is your equation. To solve for it square root of both sides then minus the 4 from both sides and you find your "n" n+4= 6 n=2 Your variable equals 2
