Solving Equations with Negatives GCSE Maths
Negative numbers often make algebra feel harder, but the method stays exactly the same. Work carefully and write every step clearly.
Example Question
Solve:
-3x + 5 = 20
Subtract 5:
-3x = 15
Divide by -3:
x = -5
Exam tip: Keep track of signs carefully. One missed negative sign can change the entire answer.
Common mistake: Students sometimes divide incorrectly when the coefficient is negative.
