Question

Solve the equation. Write a reason for each step.
𝑥 − 2 + 3(𝑥 + 2) = 3𝑥 + 10

hintHint:

Open the brackets

The correct answer is: x = 6


    SOL – It is given that 𝑥 − 2 + 3(𝑥 + 2) = 3𝑥 + 10
    Opening the brackets
    We get, x – 2 + 3x + 6 = 3x + 10
    rightwards double arrow 4x + 4 = 3x + 10      ( Adding similar terms )
    rightwards double arrow 4x – 3x = 10 – 4
    rightwards double arrow x = 6.
