Simultaneous Equations
Understand that two linear equations can be solved simultaneously by finding the point where their graphs intersect, and interpret this graphically and algebraically as the pair of values satisfying both equations
Typical age: 13–14 years
“Can your child explain that solving two equations simultaneously means finding the one pair of values that satisfies both at once — and show what that looks like on a graph?”
