If 2x - 3y = 24 and 3x + 4y = 2, what is the value of x - y ?

10

Step-by-step explanation:

2x - 3y = 24 (1)

3x + 4y = 2 (2)

(1) × 4,

8x - 12y = 96 (3)

(2) × 3,

9x + 12y = 6 (4)

(3) + (4)

17x = 96 + 6

= 102

x = 102 ÷ 17

= 6

Sub x = 6 into (2),

3(6) + 4y = 2

18 + 4y = 2

4y = 2 - 18

= -16

y = -16 ÷ 4

= -4

Therefore,

x - y = 6 - (-4)

= 6 + 4

= 10

i hope this helps you !!

good job you smart son of a gun you are smarter that einstein. 7

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
