Answer:
Simplifying
7x + -3y + 15 = 0
Reorder the terms:
15 + 7x + -3y = 0
Solving
15 + 7x + -3y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + 7x + -15 + -3y = 0 + -15
Reorder the terms:
15 + -15 + 7x + -3y = 0 + -15
Combine like terms: 15 + -15 = 0
0 + 7x + -3y = 0 + -15
7x + -3y = 0 + -15
Combine like terms: 0 + -15 = -15
7x + -3y = -15
Add '3y' to each side of the equation.
7x + -3y + 3y = -15 + 3y
Combine like terms: -3y + 3y = 0
7x + 0 = -15 + 3y
7x = -15 + 3y
Divide each side by '7'.
x = -2.142857143 + 0.4285714286y
Simplifying
x = -2.142857143 + 0.4285714286y
