13 + 2x = 3
2x = 3 - 13
2x = -10
x = -5
It is an equation and the value of x is 13/3
x = -6
It is an equation and the value of x is 2.2
-13 Plug 5 in and multiply it by -5 which equals -25 12 - 25 = -13
It is an equation and the value of y is 18
y = (13 - 3x)/2 and that cannot be simplified further.
5
x=30...9+30=39 then divide by 3 equals 13.
273 13+8 = 21 and 13*21 = 273
To find the value that, when multiplied by 13, equals 78, you would divide 78 by 13. This calculation gives you the value of 6. Therefore, 6 times 13 equals 78.
6 x 7 = 4242 - 13 = 29Check:13 + 29 = 42
n + 5 = 18 n = 13
