Answer:
Step-by-step explanation:
Simplifying
1.4x + 3.5y = 0
Solving
1.4x + 3.5y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3.5y' to each side of the equation.
1.4x + 3.5y + -3.5y = 0 + -3.5y
Combine like terms: 3.5y + -3.5y = 0.0
1.4x + 0.0 = 0 + -3.5y
1.4x = 0 + -3.5y
Remove the zero:
1.4x = -3.5y
Divide each side by '1.4'.
x = -2.5y
Simplifying
x = -2.5y
