What is the solution of the system?
gulaghasi [49]

Answer: \bold{\text{b.}\bigg(4,-\dfrac{1}{2}\bigg)}

<u>Step-by-step explanation:</u>

x - 2 = -4y  →  x = 2 - 4y

3x + 2y = 11  

3(2 - 4y) + 2y = 11     <em>replaced "x" with (2 - 4y)</em>

6  - 12y + 2y = 11     <em>distributed "3" on left side</em>

<em> </em>6   - 10y        = 11      <em>added like terms (-12y + 2y)</em>

     - 10y        =  5      <em>subtracted "6" from both sides</em>

          y         = -\dfrac{1}{2}       <em>divided both sides by -10</em>


Next, solve for x:

x = 2 - 4y

   = 2 - 4(-\frac{1}{2} )

   = 2 + 2

   = 4
