Question

If x = 3 y = 2 and z = -2. Simplify and find the value of:

a. 3(2x + y -z ) – ( 2x + 4z + y )
Simplify ___________________ value ______________
b. 4( y + 2z ) + 3 ( x+ z + y ) – ( -2x )
Simplify __________________ value _______________

Answer 1

Answer:

a) 3(2*3 + 2 - (-2)) - (2*3 + 4*(-2) + 2)

3(6+2+2) - (6-8+2)

3*10 - 0

30

b) 4(2 + 2*(-2)) + 3(3 - 2 + 2) - ( -2*3)

4(2-4) + 3*3 + 6

-8 + 9 + 6

7
