You're 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.
7X + 3Y + -3Y = 0 + -3Y
Combine like terms:
3Y + -3Y = 0
7X + 0 = 0 + -3Y
7X = 0 + -3Y
Remove the zero:
7X = -3Y
Divide each side by
'7'.
X = -0.4285714286Y
Simplifying
X = -0.4285714286Y
