Hey mate, Good evening ♡

# Here's ur answer ☆☆☆

Step-by-step explanation:

$let \: doughnuts \: be \: x \\ and \: cakes \: be \: y$

$then \: 3x + 2y = 7 \\ 5x + 4y = 13$

$multiplying \: 2 \: with \: eq1$

$6x + 4y = 14 \\ 5x + 4y = 13$

$subtracting \: eq2 \: from \: eq1$

$x = 1 \: and \: y = 2$

$cost \: of \: each \: doughnut \: is \: 1 \\ and \: cake \: is \: 2$
