Given the equation:
mx+n=px+q
Solve for x.
Solution:
In order to sovle for x, we first transpose px and n to the opposite sides of the equation, hence it must be taken to note that in transposing a number, the sign changes.
mx + n = px + q
mx - px = q - n
Factor out x in the equation mx - px.
x ( m - p ) = q - n
Divide both sides by m - p in order to determine the value of x.
x ( m - p )/( m - p ) = q - n/ m - p
x = (q - n)/(m - p)
Final answer:
x = (q - n)/(m - p)
