Webb• The subsitution method is the method most commonly used for A level. This is because it is the method used to solve linear and quadratic simultaneous equations. Example 1 Solve the simultaneous equations y= 2x+ 1 and 5x+ 3y= 14 5x+ 3(2x+ 1) = 14 5x+ 6x+ 3 = 14 11x+ 3 = 14 11x= 11 So x= 1 Using y= 2x+ 1 y= 2 × 1 + 1 So y= 3 Webb(a) Write down a pair of simultaneous equations using the above information. (b) Solve the simultaneous equations to find the values of x and y. 4. The sides of a rectangle shown …
