Solve for x: 3x − 2 &gt; 5x + 10. (5 points)
Galina-37 [17]

Answer:

x < -6

Step-by-step explanation:

3x - 2 > 5x + 10

first step is to isolate x

3x -2 >5x +10

3x > 5x + 10 + 2

3x -5x > 10 + 2

now that we have 3x and -5x we can combine them

-2x > 10 + 2

now add 10 +2 =12

-2x > 12 (now divide by -2)

x < -6 (when we divide we flip the inequality sign)
