Question

5x-2y=106

solve for x and y

Answer 1

5 x - 2y = 106

x = ( 106 + 2y ) / 5

Now, Substituting the value of x in above Eqn.

5 ( 106 + 2y) / 5 - 2y = 106

106 + 2y - 5y = 106

-3 y = 106 - 106

- 3 y = 0.

y = 0.

Similarly, putting y in x.,

x = ( 106 + 2y ) / 5

x = ( 106 + 2*0 ) / 5

x = 106 / 5 or 21.2
