Easy -1.8 This is a straightforward one-step linear inequality requiring only collecting like terms and dividing by a coefficient. It's a basic algebraic manipulation exercise with no conceptual difficulty, making it significantly easier than average A-level questions which typically involve multiple techniques or problem-solving.
M2 for \(-3 < 5x\) or \(x > \frac{3}{-5}\) or M1 for \(-5x < 3\) or \(k < 5x\) or \(-3 < kx\) [condone \(\leq\) for Ms]; if 0, allow SC1 for \(-0.6\) found
## Question 12:

|--------|-------|----------|
| $x > -0.6$ o.e. e.g. $-3/5 < x$ isw | 3 | M2 for $-3 < 5x$ or $x > \frac{3}{-5}$ or M1 for $-5x < 3$ or $k < 5x$ or $-3 < kx$ [condone $\leq$ for Ms]; if 0, allow SC1 for $-0.6$ found |
