For example when one of the equations is a quadratic. Get the coefficients to matchThe coefficients are the numbers beforexx x andyy y make thexx x. Add or subtract the equations to eliminate terms with.
Elimination this is where you multiply both equations through by different coefficient in order to eliminate one of the unknowns.
Comparing numbers up to 10. Solving Simultaneous Equations using Graphs Two equations are simultaneous if they are both true at the same time and for the same values of x and y.
