step-by-step explanation:

1)

consistent equation:  equations having a common solution in a system.

2)

Equivalent equation: equations having all common solutions.

3)

Inconsistent equations: equations having no common solutions in a system

4)

Linear inequality: an open sentence of the form Ax+By+C < 0 or Ax+By+C > 0.

5)

substitute: replace a quantity with its equal.

6)

system determinant: the determinant found when column 1 consists of the x-coefficients and column 2 consists of the y-coefficients of a linear system.

7)

x-determinant:  the determinant found when column 1 consists of the constants and column 2 consists of the y-coefficients of a linear system.

8)

y-determinant: the determinant found when column 1 consists of the x-coefficients and column 2 consists of the constants of a linear system.

step-by-step explanation:

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
