basically you asked what -28+21 which equals -7
x=-3
7+6
2+14=16
If I am correct, 9 plus 7 equals 112.
13
7 + 6 = 13
13 = 7 + s(13 - 7) = (7-7) + s6 = s
In the equation 3x plus 7 equals 13, x is equal to 2.
basically you asked what -28+21 which equals -7
273 13+8 = 21 and 13*21 = 273
-6
p + 7 = 13 p = 6
n=6
-6
-7+x=13x the -7=12x and x =-7/12
-y + 7 = 13 -y = 6 y = -6
