Answer:

k = -299/12 = - 24 11/12

Step-by-step explanation:

3x - 4 - 5(x-2) = 3/4x + 1/3 - k

x = - 7

3*(-7) - 4 - 5(-7 -2) = 3/4*(-7) + 1/3 - k

-21 -4 -5*(-9) = - 21/4 + 1/3 - k

-25 + 45 = - 21/4 + 1/3 - k

20 = (- 21*3)/(4*3) + 4/(3*4)  - k

20 = - 63/12 + 4/12 - k

20 = - 59/12 - k

k = - 59/12 - 20

k = -299/12 = - 24 11/12

Solve by graphing.
const2013 [10]

Answer:

(4,4)

Step-by-step explanation:

y = 2x - 4 -------eqn 1

4y = x + 12 ------eqn 2

From eqn 1 y = 2x - 4; insert in eqn 2

4 (2x-4) = x + 12 (open the bracket)

8x - 16 = x + 12 (taking like figures to the same side, sign changes)

8x - x = 12 + 16

7x = 28

x = 28/7

x = 4

From eqn 1

y = 2x - 4

y = 2(4) - 4

y = 8 - 4

y = 4

(x,y) = (4,4)
