16 Solve \(5x - 6 = 3(x - 1)\) (3)
| Answer | Mark | Notes |
|---|---|---|
| \(1\dfrac{1}{2}\) | M1 | for correct expansion of the bracket or dividing all terms by 3 as a first step eg \(3x - 3\) or \((5x - 6)/3 = 3(x - 1)/3\) |
| M1 | for isolating terms in \(x\) on one side of an equation eg \(5x - 6 - 3x = -3\) or both constants on one side of an equation, eg \(5x = 3x - 3 + 6\), ft \(5x - 6 = 3x - 1\) | |
| A1 | for \(1\dfrac{1}{2}\) oe |
