+37159 The second equation tells you the value of 'x' in terms of 'y'
Use this 'x' in the first equation: 13 (y+6) - 6y = 22 solve for 'y'
then use this value of 'y' in one of the equations (the second is the easiest) to find the coresponding value of 'x' Done !
+169 substitute
13(y+6)-6y=22
expand
13y+78-6y=22
isolate
13y-6y=22-78
combine
divide
done.
but you do it yourself
