First substitute the value for x Ok x=23/7 + 3/7 y. 2x-4y=-8
Second solve the equation 2(23/7 +3/7 y) -4=-8
Third substitute the value of y do y=51/11
Forth solve the equation X=23/7 +3/7 x 51/11
Fifths the possible solution is x=58/11
Sixth check the solution (x,y)=(58/11, 51,11)
Seventh simplify 7x58/11-3x51/11=23. 2x58/11-4x51/11=-8
The ordered pair is a solution 23=23. -8=-8
(x,y)=(58/11, 51,11)
