Answer:

1)

a. 4x + 2 = 14

b. 3x - 2y + 2 = 7

c. X(3y +22) = 84

d. x(2yz - xy + 3x2) = 24

e. X + z = 2

Step-by-step explanation:

1) For a-e. Evaluate the following when x = 3, y = 2 and z= -1.

a) 4x + 2

= 4(3) + 2

= 12 + 2

= 14

b) 3x - 2y + 2

= 3(3) - 2(2) + 2

= 9 - 4 + 2

= 5 + 2

= 7

c) X(3y +22)

= 3(3(2) + 22)

= 3(6 + 22)

= 3(28)

= 84

d) x(2yz - xy + 3x2)

= 3(2(2)(-1) - (3)(2) + 3(3)2)

= 3(2(-2) - 6 + (9)2)

= 3(-4 -6 + 18)

= 3(-10 + 18)

= 3(8)

= 24

e. X + z

= (3) + (-1)

= 3 - 1

= 2

I'm sorry but I'm quite confused about the other items left. It seems that there are some errors, but I'm really not sure. Anyways, I still hope this helps.
