The solution to the equation ax + b= 0 is ?
This is a linear equation in one variable : x (assuming a and b to be constants)
So by subtracting b from both LHS and RHS,
ax + b - b = 0 - b,
Thus,
ax = -b,
Dividing both LHS and RHS by a,
ax/a = -b/a,
Thus,
x=-b/a is the value of x

The solution to the equation ax + b= 0 is ?
Introduction:
The given equation is ax + b = 0. To find the solution for this equation, we need to isolate the variable x. The solution will provide the value(s) of x that satisfy the equation.
Isolating x:
To isolate x, we need to get rid of the constant term b. We can do this by subtracting b from both sides of the equation:
ax + b - b = 0 - b
This simplifies to:
ax = -b
Dividing by a:
To solve for x, we need to isolate it on one side of the equation. Since x is multiplied by a, we can divide both sides of the equation by a:
ax/a = -b/a
This simplifies to:
x = -b/a
Final Solution:
The solution to the equation ax + b = 0 is x = -b/a. This means that when the value of x is equal to -b/a, the equation will be satisfied.
Example:
Let's take a numerical example to understand this better. Suppose we have the equation 2x + 6 = 0. We can see that a = 2 and b = 6.
Using the formula x = -b/a, we can substitute the values:
x = -6/2
Simplifying this gives:
x = -3
Therefore, the solution to the equation 2x + 6 = 0 is x = -3, which means that when x is equal to -3, the equation is satisfied.
Summary:
In summary, the solution to the equation ax + b = 0 is x = -b/a. By isolating x and dividing by a, we can find the value(s) of x that satisfy the equation. This solution allows us to determine the value of x that makes the equation true.
