carmer rule method (1)3x×2y/5=20;x/3 +y=7

Answer 2

Step-by-step explanation:

$3x + \frac{2y}{5} = 20 \: (\frac{x}{3} + y) \\ 3x + \frac{2y}{5} = 20$

$multiplying \: by \: 5 \\ 15x + 2y = 100 \: \: - (1) \\ \frac{x}{3} + y = 7$

$multiplying \: by \: 3 \\ x + 3y = 21 \: \: \: - (2)$

$comparing \: both \: the \: equation$
