4n + 3 = 31n
3 = 27n
n = 3/27

4n + 3 = 15 4n +3 - 3 = 15 - 3 4n = 12 4n/4 = 12/4 n = 3
3 + 3n = 9 + 2n + 4n n = -2
N=3.
4n+13=1 -13 -134n=-12/4 /4n=-3
n= -2
4n + 3 = 19Subtract 3 from each side:4n = 16Divide each side by 4:n = 4
4n + 9 = -3 Now, we take away 9 from both sides 4n = -12 Now divide by 4 n = -3
3n+18 = 39 -4n 3n+4n = 39 -18 7n = 21 n = 3
6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n
7n + 2 = 4n + 17Subtract 2 from each side:7n = 4n + 15Subtract 4n from each side:3n = 15Divide each side by 3:n = 5
To solve the equation 4n + 3 = 31, you will first subtract 3 from both sides of the equation to isolate the term with n. This gives you 4n = 28. Then, you divide both sides of the equation by 4 to solve for n. So, n = 7.
