Question

Solve for x and y, 149x + 330y = -511 and 330x + 149y = -32

Answer 1

Step-by-step explanation:

Given,

149x + 330y = -511———(i)

330x + 149y = -32———(ii)

Now,

From Equation (i),

149x + 330y = -511

or,x = - 16/165 - 149/330y

Substitute the value of 'x' in equation (i),

149(16/165 - 149/330y) + 330y = -511

or,y = - 163862/86699

Substitute the value of 'y' in equation (ii),

x = - 16/165 - 149/330(- 163862/86699)

or,x = 65579/86699

(x,y) = (65579/86699 , - 163862/86699)
