Question

What is the solution set of 4x = y and 2x2 − y = 0?

Answer 1

Answer:

$y = 4x \\ \\ y = 2 {x}^{2} \\ \\ b y\: \: equations \: \: = > \\ \\ 2 {x}^{2} = 4x \\ \\ x = 0 \: \: \: \: \: \: and \: \: \: \: \: x = 2 \\ \\ y = 0 \: \: \: \: \: and \: \: \: \: \: y = 8$

$4x = y \\ \\ 2{x}^{2} - y = 0 \\ \\ \: \: \: \: \: \: \: \: or \\ \\ 4x = y \: \: \: \: \: \: ......(i) \\ \\ 2 {x}^{2} = y \: \: \: \: \: ........(ii) \\ \\ from \: (i) \: and \: (ii) \\ \\ 4x = 2 {x}^{2} \\ \\ <strong><em><u>x = 2</u></em></strong> \\ \\ and \\ \\ y = 4x \\ \\ <strong><em><u>y = 8</u></em></strong>$
