What is 8 - 3x > -25 because i have been wondering all day
Svetllana [295]

Answer:

8 - 3x > -25 : \left[\begin{array}{ccc}solution: x < 11\\Interval Notation:(-\infty,11)\end{array}\right]

Step-by-step explanation:

8-3x>-25

Subtract 8 from both sides:

8-3x-8>-25-8

Simplify:

-3x>-33

Multiply both sides by -1 (reverse the inequality):

\left(-3x\right)\left(-1\right)

Simplify:

3x

Divide both sides by 3 :

\frac{3x}{3}

Simplify:

x < 11
