4400 Higher November 2007 Paper 3 Q14
14 Solve the simultaneous equations
\[2x + 5y = 16\]\[4x + 3y = 11\](3)
| Scheme | Marks |
|---|---|
| \(4x + 10y = 32\) or \(x = (16 - 5y)/2\) or similar | M1 |
| \(x = \frac{1}{2}\), \(y = 3\) | A1A1 |
| (3) | |
| (3 marks) |
Notes
M1: Mult so coeffs of \(x\) or \(y\) are equal or make \(x\) or \(y\) subject
Allow error in constant term
