Answer:
Explanation:
Simplifying
12x + -3y = 12
Solving
12x + -3y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
12x + -3y + 3y = 12 + 3y
Combine like terms: -3y + 3y = 0
12x + 0 = 12 + 3y
12x = 12 + 3y
Divide each side by '12'.
x = 1 + 0.25y
Simplifying
x = 1 + 0.25y
