Solve the inequality 5x7 &lt; 2x - 1
Vanyuwa [196]

x is strictly less than 2 or x ∈ (-∞, 2)

Given: inequality 5x - 7 < 2x - 1

What are inequalities?

Inequalities are statements that are represented as comparison between two or more numbers or algebraic expressions.(strictly less, strictly great, greater, lesser)

Solving the given equation:

5x - 7 < 2x - 1

=> 5x - 7 - 2x < 2x - 1 - 2x

=> 3x - 7 < -1

=> 3x - 7 + 7 < -1 + 7

=> 3x < 6

=> x < 2

Therefore, x is strictly less than 2.

Hence x ∈ (-∞, 2)

The number line is attached below.
