Question

Solve 7x + 1 < 4(x - 2).

Answer 1

x < -3.

Explanation:

7x + 1 < 4(x - 2)

7x + 1 < 4x - 8

7x - 4x < -8 - 1

3x < -9

x < -3.

Answer 2

x < - 3

Explanation:

Given

7x + 1 < 4(x - 2) ← distribute parenthesis on right side

7x + 1 < 4x - 8 ( subtract 4x from both sides )

3x + 1 < - 8 ( subtract 1 from both sides )

3x < - 9 ( divide both sides by 3 )

x < - 3
