Answer:
-0.25y
Explanation:
Simplifying
4x + 1y = 12
Solving
4x + 1y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1y' to each side of the equation.
4x + 1y + -1y = 12 + -1y
Combine like terms: 1y + -1y = 0
4x + 0 = 12 + -1y
4x = 12 + -1y
Divide each side by '4'.
x = 3 + -0.25y
Simplifying
x = 3 + -0.25y
