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
y = (13 - 3x)/2 and that cannot be simplified further.
5
It is an equation and the value of y is 18
x=30...9+30=39 then divide by 3 equals 13.
273 13+8 = 21 and 13*21 = 273
6 x 7 = 4242 - 13 = 29Check:13 + 29 = 42
6x+13 is just 6x+13 you can not combine the terms because they are not like terms. ifyou make this expression equal a value... lets say 1 then you can find a value for "x" 6x+13=1 6x+13-13=1-13 6x=-12 x=-2
4 x 3 + 1 = 13
