22n + 2.

10n+2

Gather like terms. The - 2 and 4; the 7n and 3n. 7n - 2 + 3n + 4 = 10n + 2

3n + 4n = -14 7n /7 = -14 /7 n = -2

All you do is look for like terms such as 7n and 3n; 2 and 8 Then you do 7n+3n=10 n And ........... 2-8=-6 The answer is 10n-6 if you still dont get it contact me(:

10n + 3 = 7n + 53n = 2n = 2/3

(10, 2)

(3n-2)/8 = (n+4)/55(3n - 2) = (n+4)815n - 10 = 8n + 327n = 42n = 6

2 - 7n = 6therefore 7n = 2 - 6 = -4 and so n = -4/7 Then 5m + 7n = 6.4 becomes 5m - 4 = 6.4 so that 5m = 10.4 and then m = 10.4/5 = 2.08

3n+2+3n+2=6n+4

7n + 2 = 4n + 17Subtract 2 from each side:7n = 4n + 15Subtract 4n from each side:3n = 15Divide each side by 3:n = 5

3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6

3n+1=7 3*2+1=7

4n

9n-2=7n+50 7n+9n=50+2 16n=52 n= 3.25

3 + 3n = 9 + 2n + 4n n = -2

m + 3n = 7n = -2017n = -201n = -201 / 7n = -28.71m + 3n = -201m + 3(-28.31) = -201m - 86.14 = -201m = -201 + 86.14m = -115So the final answer will be, m = -115 and n = -28.71I hope this makes sense. :)

7n -1n,0n,1n,2n,3n,4n,5n,6n,7n 1 2 3 4 5 6 7 8 9

perimeter equals 2 times width plus 2 times length so, perimeter equals 2(3n+2)+2(n-1) = 6n+6+2n-2 = 8n+4.

2 - 4N = 2 + 3NSubtract 2 from each side:-4N = 3NAdd 4N to each side:0 = 7NN = 0That's the only value of ' N ' for which the given equationcan become a true statement.

-7n - 8 + 6 = 13 - 2 Add 2 to each side: -7n - 8 + 6 + 2 = 13 simplify: -7n = 13 n = -13/7 = -16/7

3n+2 + (3n+3 - 3n+1) = 3n+1+1 + (3n+1+2 - 3n+1) = 3*3n+1 + (9*3n+1 - 3n+1)= (3+9-1)*3n+1 = 11*3n+1.

4n-8=3n+2 4n=3n+2+8 4n=3n+10 4n-3n+10 n=10 N = 10

3n+6=18 n+2=6 n=4
