Three times a certain number (x), minus 2 is less than the number minus 6.Find the possible values of x.
x <-2
x>2
x>-2
x<2
Correct answer is A
Three times a certain number (x) = 3x
minus 2 = -2
is less than = <
the number minus 6 = x -6
Mathematically; 3x - 2 < x - 6
collect like terms
3x - x < -6 + 2
2x < -4
x < -2 is the possible values of x
