If 2x - 3y = 24 and 3x + 4y = 2, what is the value of x - y ?
Reika [66]

Answer:

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

Find the solution set.<br><br> x −2 / x−9 =2
klemol [59]

\dfrac{x-2}{x-9} =2

The denominator can't be equal to 0, so

x-9\neq 0\\x\neq 9

Now we can solve the equation

\dfrac{x-2}{x-9} =2\\\dfrac{x-2}{x-9}=\dfrac{2x-18}{x-9}  \\x-2=2x-18\\-x=-16\\x=16

Answer: x=16
