Question

write DX for the simultaneous equation 5x+2y=10;-3x+y=+1​

Answer 1

Answer

5x + 2y = 10 \\ = 5x + 2y + - 2y = 10 + - 2y \\= 5x = - 2y + 10 \\ = \frac{5x}{5} = \frac{ - 2y + 10}{5} \\ = x = \frac{ - 2}{5} y + 2 \: \: answer[/tex]

$- 3x + y = 1 \\ = 3x + y + - y = 1 + - y \\ = - 3x = - y + 1 \\ = \frac{ - 3x}{ - 3} = \frac{ - y + 1}{ - 3} \\ = x = \frac{1}{3} y + \frac{ - 1}{3} \: \: \: answer$
