The solution for 5x = y + 6, 2x - 3y = 4 is x = 14/13, y = -8/13.

From 5x = y + 6 , we can get y = 5x - 6, which we can put it into the 2th equation.

2x - 3y = 4

2x - 3 (5x - 6) =4

-13x + 18 =4

x = 14/13

put x = 14/13 into the y = 5x - 6 , we can get the value of y

y= 5x - 6

y= 5*14/13 - 78/13

y= 70/13-78/13

y= - 8/13

From 5x = y + 6 , we can get y = 5x - 6, which we can put it into the 2th equation.

2x - 3y = 4

2x - 3 (5x - 6) =4

-13x + 18 =4

x = 14/13

put x = 14/13 into the y = 5x - 6 , we can get the value of y

y= 5x - 6

y= 5*14/13 - 78/13

y= 70/13-78/13

y= - 8/13
