If n + 7 = 12, then n = 12 - 7
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
6+8=14
4y + 7 = 19 ∴ 4y = 12 ∴ y = 3
3t + 7 = 2t - 5 3t = 2t - 12 t = -12
The answer to 12 P plus 7 times 139 equals 39. This is taught in high school math.
yes. think of 6/12 plus 1/12. that is 7/12!
It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
It cannot because neither statement is true.
If: x+3+6x+9 = 0 then 7x+12 = 0 So: 7x = -12 and x = -12/7
n= -2
x=7
7
