2x – 4 < 3x + 21 solve the inequality

Isolate the x. Subtract 3x from both sides, and add 4 to both sides

-2x (-3x) - 4 (+4) < 3x (-3x) + 21 (+4)

-2x - 3x < 21 + 4

Simplify. Combine like terms

-5x < 25

Isolate the x. Divide -5 from both sides (remember to flip the sign).

-5x/-5 < 25/-5

x > 25/-5

x > -5

x > -5 is your answer

hope this helps
