Rzqust [24]

Answer:

Step-by-step explanation:

First you need to convert it to a linear expression.

3x - y = 4

+3x        +3x

-1y = 3x + 4

---  ----- -----

-1     -1    -1

y = -3x -4

6x - 2y = 7

-6x         -6x

-2y = -6x + 7

----    -----   -----

-2       -2     -2

y = 3x - 3.5

-3x - 4 = 3x - 3.5

+3x         +3x

-4 = 6x - 3.5

+3.5       +3.5

-0.5 = 6x

-----   -----

6         6

-0.5

------ =  x
