2/3 +4/6 =
x+3=14 x+3-3 = 14-3 (subtract 3 from both sides to solve for x) x = 11
3x-2 = 2x+3 3x-2x = 3+2 x = 5
2z+6z+24=0 8z+24=0 8z= -24 z= - 3
2x2+1x-3=0 4+x-3=0 x+1+0 x=-1 is your final answer
n= -2
It can be simplified to: 9m-2n
You can't. 17 + 2n = 21 + 2n gives: 2n = 4 + 2n which gives 0=4 which is not possible so the sum is not solveable.
5-2n=3 -2n=3-5 -2n=-2 n=1
n + 2 = 5, solve for n.n = 5 - 2n = 3
2n plus 5 n would be 7n and its impossible to solve the value of n.
2n + 3 = 352n = 35 -32n = 32n = 32/2n = 16
12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
3n - 2n = n 3n - 2n = (3 - 2)n = 1n = n
3 + 3n = 9 + 2n + 4n n = -2
18n + 27 or 9(2n + 3)
2n/3 = 4 2n = 3*4 2n = 12 n = 6 :)
