Question 1205685
<pre>
x=y-5

3x+y=1

x = y - 5___x - y = - 5 ----- eq (i)
           3x + y = 1 ------- eq (ii)
               4x = - 4 ----- Adding eqs (i) & (ii)
              {{{highlight_green(matrix(1,5, highlight(x), "=", (- 4)/4, "=", highlight(- 1)))}}}

Proceed by substituting - 1 for x into any of the 2 equations to get the value of y.</pre>
