The equation y = mx + b is used to express the equation of a line. Which solution is a correct way to solve this equation for x
MariettaO [177]

By first subtraction b and then dividing by m, the solution of the linear equation for x is:

(y - b)/m = x

<h3>How to solve the linear equation for x?</h3>

Here we have a linear equation that defines the variable y in terms of the variable x:

y = m*x + b

Where m and b are real numbers.

Now we want to find x in terms of the variable y, this means that we need to isolate the variable x.

if first we subtract b in both sides, we get:

y - b = m*x + b - b

y - b = m*x

If now we divide both sides by m, we get:

(y - b)/m = m*x/m

(y - b)/m = x

This is the linear equation solved for x.
