Easy -1.8 This is a straightforward two-equation system with simple coefficients requiring only substitution and basic algebra. It's significantly easier than average A-level content—more of a GCSE-level skill check with minimal computational complexity and no conceptual challenge.
or multiplication/division to make one pair of coefficients the same; condone one error in either method
simplification to \(ax=b\) or \(ax-b=0\), or equivalent for \(y\)
M1
or appropriate subtraction/addition; condone one further error; independent of first M1
\((9/7, 22/7)\) oe or \(x=9/7\), \(y=22/7\) oe isw
A2 (A1 each)
A0 for just rounded decimals or for \(-9/-7\) oe [4]
# Question 2:
substitution to eliminate one variable | M1 | or multiplication/division to make one pair of coefficients the same; condone one error in either method
simplification to $ax=b$ or $ax-b=0$, or equivalent for $y$ | M1 | or appropriate subtraction/addition; condone one further error; independent of first M1
$(9/7, 22/7)$ oe or $x=9/7$, $y=22/7$ oe isw | A2 (**A1** each) | A0 for just rounded decimals or for $-9/-7$ oe [4]
