Solve the simultaneous equation: x+2y=8 and 2x+y=10 - using a calculator

Make the x's the same in order to remove the x's from the eqn Multiply eqn (1) by 2 and keep eqn (2) the same to gain 2x+4y=16 and 2x+y=10To get rid of the x's, subtract: eqn (1) - eqn (2)4-1y = 16-10 which equates to 3y = 6 To find y by itself, divide 6 by 3 = 2 To find x, substitute into either eqn (1) or (2) - e.g. eqn (1): x + 2(2) = 8 therefore x=4 More instructions will be provided on the whiteboard
