I'm kinda stumped on this

solve -4x + x = - 9/4

  x = 3/4

Step-by-step explanation:

It usually works well to collect terms first. (Add the coefficients of x.)

  -4x +x = -9/4

  (-4+1)x = -9/4

  -3x = -9/4 . . . . . . equation with terms collected

Now, you can divide by the coefficient of x. Here, it can be useful to consider this to be the same as multiplying by the inverse of that coefficient, which inverse is -1/3.

  (-1/3)(-3x) = (-1/3)(-9/4) . . . . . multiply both sides by -1/3

  x = 3/4 . . . . . simplify

x=30

step-by-step explanation:

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
