Solve the equation 3/2*x - 1 = 5 Solution Supposing that (3/2) is the coefficient of x, we\'ll solve the equation (3/2)*x - 1 = 5. First, we have to add, both sides of the equation, the value 1. (3/2)*x - 1 + 1 = 5 + 1 (3/2)*x = 6 We can see that x is multiplied by (3/2), so we have to multiply both sides of the equation with the inverse ratio (2/3), to undone what it has been made to the unknown x. (3/2)*x*(2/3) = 6*(2/3) x=4.
