Question

Question 12.
Subtract 3x - 5y-2 from 5y - 3x2 + xy and find the value of the result if x = 2, y=-1.​

Answer 1

Answer:

-22

Explanation:

We need to subtract 3x-5y-2 from 5y-6+xy

i.e,(5y-6+xy)-(3x-5y-2)

=5y-6+xy-3x+5y+2

=10y-3x-4+xy

Now, if x=2 and y=-1

10y-3x-4+xy =10(-1)-3(2)-4+(2)(-1)

=-10-6-4-2

=-22

ANSWER IS -22
