Amazing teaching! Just wondering, because I think toy have made a mistake, but I'm not sure. When it says the question '3x - 5y = -31 and 4x - 2y = -18, you said that 6x - 20x = 14 but it's actually -14. Thne you made the answer as -2. I think the answer is actually 2 because -14 ÷ 14 is -x and -28 ÷ -14 = -2 (showing -x = -2) which would equal to x = 2 instead.

@GCSEALevelMaths Год назад

If you multiply the second equation by 2 you get 2x+6y=20 and then you would subtract 2x+3y=14 so you would get 3y=6 therefore y=2. sub in y=2 to work out value of x. x is 4 x=4 hope it made sense sorry for the late response.
