The inequality is solved to give x ≥ 11
First, we need to know that inequalities are mathematical expressions that compare two values, showing their relative sizes.
Inequalities are used to represent ranges, constraints, or conditions in various mathematical problems and real-world situations.
Then, we have from the information given that;
x + 7 ≥ 18
To solve the inequality, collect like terms, we get that;
x ≥ 18 - 7
subtract the values, we get;
x ≥ 11
Thus, the inequality is solved to give x ≥ 11
