<pre>
I am having trouble solving this equation its so simple but i cant remember please help.

5x-3y=4
y-x=-2

solving by substitution method please show me how to solve I am not getting the answer right.

The following response from the other person is RUBBISH!!! Hopefully, no one pays attention to it!
X-Y=-2 OR X=Y-2 THEN SUBSTITUTING (Y-2) FOR X IN THE FIRST EQUATION WE GET
5(Y-2)-3Y=4 OR 5Y-10-3Y=4 OR 2Y=4+10 OR 2Y=14 OR Y=14/2 OR Y=7
THEN X-7=-2 OR X=-2+7 OR X=5
PROOF 5(7-2)-3*7=4 OR 5*5-21=4 OR 25-21=4 OR 4=4

===============
                5x - 3y = 4 ---- eq (i)
                    y - x = - 2___y + 2 = x ---- eq (ii)

                5x - 3y = 4 ---- eq (i)
      5(y + 2) - 3y = 4 ---- Substituting y + 2 for x in eq (i)
       5y + 10 - 3y = 4
                5y - 3y = 4 - 10
                        2y = - 6
                         {{{highlight(y = (- 6)/2 = - 3)}}}

                    y + 2 = x ---- eq (ii)
                 - 3 + 2 = x ---- Substituting - 3 for y in eq (ii)
                        - 1 = x
Solution set: {{{highlight(system(x = - 1, y = - 3))}}}

You can do the check!!</font></font></font></b></pre>
