Question

solution set of the inequation 7x+9>30 is​

Answer 1

Linear Inequations: Mathematical expressions help us convert problem statements into entities and thus, help solve them. If the expression equates two expressions or values, then it is called an equation. For e.g. 3x + 5y = 8. On the other hand, if an expression relates two expressions or values with a ‘<’ (less than) sign, ‘>’ (greater than) sign, ‘≤’ (less than or equal) sign or ‘≥’ (greater than or equal) sign, then it is called as an Inequality.

An inequality which involves a linear function is a linear inequality. It looks like a linear equation, except that the ‘=’ sign is replaced by an inequality sign, called linear inequations. In this article, we will look at linear inequalities with one or two variables
