SSN26 Explanation!

Given #1:

2xy - 3x if x = 2, y = 4

Solution:

*You just need to substitute the values*

2xy - 3x

2(2)(4) - 3(2)

16 - 6

10

Given #2:

-5y - 13x if x = -2 y = 2

Solution:

*You just need to substitute the values*

-5y - 13x

-5(2) - 13(-2)

10 + 26

36

Given #3:

12 + 10 xy - 13 if x = 4; y =-3

Solution:

*You just need to substitute the values*

12 + 10 xy - 13

12 + 10(4)(-3) - 13

12 - 120 -13

-121
