BECE Mathematics 2019 Paper

Concept:Let the number of boys be represented by a variable and form a simple linear equation from the total students.Explanation:Let the number of boys be $x$.The girls are 7 more than the boys, so girls $= x + 7$.Total students in the class $= 23$.Therefore, $x + (x + 7) = 23$.Simplifying: $2x + 7 = 23$.Subtract 7 from both sides: $2x = 16$.Divide both sides by 2: $x = 8$.So, there were 8 boys in the class.Answer:The number of boys is $8$.
