Question

1 - 2x + 3y for x = -2 and y= -5

Answer 1

Answer:

All you need to do is plug the values and then simplify!

$\large{ \tt{ - 2x + 3y}}$

• Plug the value of x and y :

$\longrightarrow \: \large{ \tt{ - 2 \times ( - 2) + 3 \times ( - 5)}}$

• When negative integer is multiplied by negative integers , we get positive integer & when positive integer is multiplied by negative integer , we get negative integer.

$\longrightarrow \large{ \tt4 + ( - 15){}}$

$\longrightarrow \large{ \tt{4 - 15}}$

$\longrightarrow{ \large{ \boxed{ \tt{ - 11}}}}$

• Hence , Our simplified answer is -11 .
