4 x − 6 x + 2 = 3 x ⋅ 12 3 x − 2 ( x + 2 ) = 4 x 3 x − 2 x − 4 = 4 x 3 x − 2 x − 4 x = 4 − 3 x = 4 / : ( − 3 ) x = − 3 4 x = − 1 3 1
4 x − 6 x + 2 = 3 1 / ⋅ 12 4 x ⋅ 12 − 6 x + 2 ⋅ 12 = 3 1 ⋅ 12 3 x − 2 ( x + 2 ) = 4 3 x − 2 x − 4 = 4 x = 8
The solution to the equation 4 x − x + 6 2 = 3 x is x = 13 4 . This result was achieved by eliminating fractions and combining like terms. A substitution of the solution confirms its validity in the original equation.
