To solve ax + by + c = 0 for x, isolate x by subtracting ax and dividing by b, resulting in x = (-b/a)y - (c/a).
To solve for x in the equation ax + by + c = 0:
Isolate the x term: Subtract ax from both sides of the equation:
ax + by + c - ax = 0 - ax
by + c = -ax
Combine constant terms: Move the constant term to the right side of the equation:
by = -ax - c
Isolate x: Divide both sides by the coefficient of x (b):
b * (by) = b * (-ax - c)
y = (-a/b)x - (c/b)
Rewrite the equation in terms of x:
x = (-b/a)y - (c/a)
Therefore, the solution for x in the equation ax + by + c = 0 is x = (-b/a)y - (c/a).
