Question

Tonya wrote the equation below which solves for x.

x=150-6y

Which equation is equivalent to Tonya’s equation?

Answer 1

x+6y=150

Explanation:

If you add 6y to both sides of the equation, it becomes this, making it equal.

Answer 2

x+6y = 150 (B)

Explanation:

Given the equation x = 150-6y

The equation is also equivalent to

x+6y = 150.

This is gotten simply by taking -6y to the other side of the equation but note that if a function or constant is crossing an 'equal to' sign in an equation, it changes the sign. Considering this equation, -6y changed to +6y upon crossing the equal to sign to give is x+6y = 150 which is the required answer.
