3n+5=2n+7 subtract 2n on both sides.
n+5=7 subtract 5 to the other side.
n=2 the answer to n is 2.
Hoped that helped. (:

Subtract 2n from each side: 3n - 9 = 6 Add 9 to each side: 3n = 15 Divide both sides by 3: n = 5 Therefore, n = 5
first combine like terms and 5n+7=-41 add -7 to both sides 5n=-48 n=-48/5
2n + 5 = 25 < ---------------- Write the Equation 2n = 20
6=(1-2n)+5 6-5=(1-2n)+5-5 1=1-2n 1-1=1-1-2n 0=-2n 0/-2=-2n/-2 0=n
10: 3n = 2(n + 5); 3n = 2n + 10; (subtract 2n from each side) n = 10.
