Cambridge IGCSE Mathematics practice

exam practice - 1 Create basic expressions and equations, such as expressing a number that is 2 more than n, including forming linear simultaneous equations. 2 Solve linear equations with one variable, for example: 3x + 4 = 10. 3 Solve simultaneous linear equations involving two variables, such as: 5 - 2x = 3(x + 7). 4 Rearrange simple formulas to make a specific variable the subject, including cases where the variable appears only once and does not involve powers or roots. - Equations
