To determine the value of x in the given equation we need to substitute the values of other variables mentioned in the question.
Given,
x(a - b) = m(x - c)
Let us now substitute the value of a,b,c and m in the given equation
=> x(1 - 8) = 2(x - 3)
=> x(-7) = 2x - 6
=> -7x = 2x - 6
=> -7x - 2x = -6
=> -9x = -6
=> x = 6/9
On further simplification,
x = 2/3
Therefore the value of x calculated from the given equation is 2/3
