Answer 2

Answer:

-74 or 2

Step-by-step explanation:

As x = 2 and y= 1

since 5x is together you multiply it to 2 so 5 x 2 = 10

since 4xy is together you multiply it to 21 so 4 x 21 = 84

so than 10-84

which would equal to -74

so answer could be -74

Or

since 4xy is together you multiply it to 2 and 1 so 4 x 2 = 8x 1 = 8

so 10-8 would equal to 2

so answer could be 2
