30 Solve the simultaneous equations
\(3x + y = -4.5\)
\(4x + 3y = -3.5\) (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| \(x = -2\) \(y = 1.5\) | M1 | for correct method to eliminate either \(x\) or \(y\) or a method leading to substitution |
| M1 | (dep M1) for substituting found value in one of the equations or correct method after starting again | |
| A1 | for \(x = -2\) and \(y = 1.5\) oe |
Additional guidance
condone one arithmetic error (both M marks)
