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:

$x < 11$

Hope I helped. If so, may I get brainliest and a thanks?

Thank you, have a good day! =)
