28 Solve the simultaneous equations (3)
\[\begin{aligned} 5x + 2y &= 27 \\ 6x + 4y &= 28 \end{aligned}\]| Answer | Mark | Mark scheme |
|---|---|---|
| \(x = 6.5,\) \(y = -2.75\) | M1 | for a correct method to eliminate either \(x\) or \(y\) or method leading to substitution |
| M1 | (dep) for substituting found value in one of the equations OR correct method after starting again | |
| A1 | for \(x = 6.5\), \(y = -2.75\) oe |
