Answer:
2x + y - 5 = 0, y = -1/-3x
Step-by-step explanation:
Q. 2x + y = 5
Ans :- 2x + y = 5
Move the constant to the left-hand side by adding it's opposite to both sides.
= 2x + y - 5 = 5 - 5
The sum of two opposites equal 0.
= 2x + y - 5 = 0
Q. x + 3y = 0
Ans :- x + 3y = 0
Move the variable to the right-hand side and change its side.
= 3y = - x
Divide both sides of the equation by 3.
= y = -1/-3x
