2x +1 < 5 what would be the inequality for this ?

Juli2301 [7.4K]

Hey there!

2x + 1 < 5

SUBTRACT 1 to BOTH SIDES

2x + 1 - 1 < 5 - 1

SIMPLIFY IT!
2x < 5 - 1

2x < 4

DIVIDE 2 to BOTH SIDES

2x/2 < 4/2

SIMPLIFY IT!
x < 4/2

x < 2

Therefore, your answer is: x < 2

(The graph is down below)

Good luck on your assignment & enjoy your day!
