Question

Solve the inequality 5(2x + 1) < 10.

х< 1/2
x> 1/2
х< 3/2
x> 3/2

Answer 1

x < 1 / 2

Explanation:

10x + 5 < 10

10x < 5

x < 5 / 10

x < 1 / 2

Answer 2

x < 1/2

Explanation:

5(2x + 1) < 10

Divide each side by 5

5/5(2x + 1) < 10/5

2x+1 < 2

Subtract 1 from each side

2x+1-1 < 2-1

2x <1

Divide each side by 2

2x/2 <1/2

x < 1/2
