Explanation

Let Khadija's current age be x years. After one year her age is x + 1 years, and ten years ago it was x − 10 years, so x + 1 = 2(x − 10), giving x + 1 = 2x − 20 and x = 21 years. The likely mistake is option b, 20 years, from ignoring the phrase “after one year.”

About Linear Equations

Linear equations contain variables only to the first power and produce straight-line relationships when represented graphically. Problems involve solving equations with brackets, fractions, and variables on both sides, forming equations from statements, and handling simultaneous linear equations, which differ from quadratic equations by having no squared variable.
