Please help me on this question

a. 1

b. 3

c. 9

Step-by-step explanation:

all you have to do is plug in 2 to the equations as x and solve for y!

a.

y = 7 - 3(2)

y = 7 - 6

y = 1

b.

y = (2)^2 -1

y = 4 -1

y = 3

c.

y = (18/(2))

y = 9

lmk if you need more of an explanation but that's pretty much all the work you need i think!! :)
