Объяснение:

$30x - 4by + 4ay - 3bx = 30 \times 5 - 4 \times 7 \times 3 + 4 \times 8 \times 3 - 3 \times 7 \times 5 = 150 - 84 + 96 - 105 = 57$

Answer 2

To evaluate the expression $30x - 4by + 4ay - 3bx$ with the given values of $a$, $b$, $x$, and $y$, we substitute the values into the expression:

$a = 8$

$b = 7$

$x = 5$

$y = 3$

Substitute these values into the expression:

$30x - 4by + 4ay - 3bx$

$= 30 \times 5 - 4 \times 7 \times 3 + 4 \times 8 \times 3 - 3 \times 7 \times 5$

$= 150 - 84 + 96 - 105$

$= 157$
