Question

Simplify the expression and find its value,
when x = -1 and y = 2.
2x²– 3y + 3x² + 5y²+ 5x - 7 - 7x + 2y​

Answer 1

Answer:

$2x$

$2$

$- 3y + 3x$

$2 + 5x$

$+ 5x - 7 - 7x + 2y$

$= 10x$

$2 - 2x - y - 7$

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

$10( - 1)$

$2( - 1) - 2 - 7$

$= 10 + 2 - 2 - 7$

$= 3$

$value \: = 3$
