Question

37x - 39y = 150, 39x - 37y = 154 using substitute method​

Answer 1

Answer:

39x = 37y + 154

x = 37y/39 + 154/39

// Plug this in for variable x in equation [1]

[1] 37•(37y/39+154/39) - 39y = 150

[1] - 152y/39 = 152/39

[1] - 152y = 152

// Solve equation [1] for the variable y

[1] 152y = - 152

[1] y = - 1

// By now we know this much :

x = 37y/39+154/39

y = -1

// Use the y value to solve for x

x = (37/39)(-1)+154/39 = 3
