(a) Solve \(14n \gt 11n + 6\) (2)
(b) On the number line below, show the set of values of \(x\) for which \(-2 \lt x + 3 \leqslant 4\)
| Answer | Mark | Mark scheme |
|---|---|---|
| \(n \gt 2\) | M1 | for a method to isolate terms in \(n\) in any inequality or equation eg. \(14n - 11n \gt 6\) or \(n = 2\) |
| A1 | cao |
Additional guidance
Ignore incorrect inequality sign and accept “=” sign
| Answer | Mark | Mark scheme |
|---|---|---|
 | M1 | for \(-2 - 3 \lt x \leqslant 4 - 3\ (-5 \lt x \leqslant 1)\) |
| M1 | for drawing a line from \(-5\) to 1 or (indep) for an open circle at either \(-2\) or \(-5\) or (indep) for a closed circle at 4 or 1 | |
| A1 | cao |
Additional guidance
For the first M1: A circle around \(-5\) and 1 implies M1
For the second M1: A line from \(-5\) to 1 implies M2 if no working shown
