Best ResponseYou've already chosen the best response.0Write 3x + 5y = 1 (a) y = 2x  8 (b) Now substitute the value of y in (b) into (a) Giving 3x + 5(2x 8) = 1 Expand and simplify to find the value of x 3x +10x  40 = 1 13x = 39 Therefore x = 3 Now substitute this value of x into (b) y = 2(3)  8 Therefore y = 6  8 = 2 Answer = x is 3 and y is 2
