A) x and y are two numbers taken from the list below.

9

o

10

(i) What values of x and y will make 3x - 2y equal zero? x = 6

V

Work out the greatest possible value of 3x - 2y.

ii) Work out the least possible value of 3x - 2y.

b) Find the value of 5(a - 4b) when a = -7 and b =

(i) values of x and y that will make 3x - 2y equal zero is when x = 6 and y = 9.

ii) The greatest possible value of 3x - 2y will be when x = 10 and y = 0.

iii) The least possible value of 3x - 2y will be when x = 0 and y = 10.

Step by step explanations:

(i) values of x and y will make 3x - 2y equal zero is x = 6 and y = 9.

3x - 2y = 0

3(6) - 2y = 0

18 = 2y

y = 9.

ii) The greatest possible value of 3x - 2y will be when x = 10 and y = 0.

3x -2y

=3(10) - 2(0)

= 30-0

= 30

iii) The least possible value of 3x - 2y will be when x = 0 and y = 10.

3x -2y

=3(0) - 2(10)

= 0-20

= -20

Kindly complete the question b.

B) Find the value of 5(a - 4b) when a = -7 and b = what?
