Question

Solve for x and y or solve the following equation 2x+y=3 and x+3y=1

Answer 1

Step-by-step explanation:

here we are given 2x + y = 3

y = 3 - 2x ... eq.(1)

putting the value of y = 3 - 2x in the equation x + 3y

therefore, x + 3 ( 3 - 2x) = 1

x + 9 - 6x = 1

9 - 5x = 1

9 - 1 = 5x

8 = 5x

x = 8/5. ok
