Answer

7(2x+4) + 12x$

QNO2 (i): Solve and represent on real line: 2=7(2x+4)+12x2 = 7(2x+4) + 12x Step 1: Expand the right side of the equation. 2=14x+28+12x2 = 14x + 28 + 12x Step 2: Combine like terms on the right side. 2=26x+282 = 26x + 28 Step 3: Isolate xx. Subtract 28 from both sides. 2−28=26x2 - 28 = 26x −26=26x-26 = 26x Divide by 26. x=−2626x = \frac{-26}{26} x=−1x = -1 Step
