Question

2. y + 2x = 12 for D = {2,3,4} ty X у 10 2 6) r-7 = 13 3 4 5

Answer 1

we have

y+2x=12

The domain D is (2,3,4)

Find the values of y for each value of x

so

For x=2

substitute in the equation

y+2(2)=12

y+4=12

solve for y

y=12-4

y=8

For x=3

y+2(3)=12

y+6=12

y=12-6

y=6

For x=4

y+2(4)=12

y+8=12

y=12-8

y=4
