The answer will depend on the relationship between x and y. Since you have chosen not to share that information, it is not possible to give a more precise answer.
It is an equation and the value of x is 13/3
If you mean x+4 = 13 then the value of x is 9
Yes that is correct
2x+3y=13 3x-y=3 x=2
13 to the 6th power equals 4,826,809
40
Because the value of C equals 13
I assume you mean what is the solution for the value of n. 4n+11-7n = -13 -3n = -24 n=8
13 ? 15
The value of x is 4.2
13 tens is the same as 13 x 10 which equals 130.

P=19. Just add 13 & 6 to obtain value.
-13 Plug 5 in and multiply it by -5 which equals -25 12 - 25 = -13
It is an equation and the value of x is 91
If: 9/N = 13/7 Then: N = 63/13 or 52 and 11/13
x=30...9+30=39 then divide by 3 equals 13.
