This equation has one solution. 3(x – 2) + 4x = 10(x + 1)

Equation: 3(x – 2) + 4x = 10(x + 1)

3(x – 2) + 4x = 10(x + 1)

= 3x - 6 + 4x = 10x + 10

By adding the - 10x - 10 on both sides of equation:

= 4x + 3x - 10x - 6 - 10 = 10x + 10 - 10x - 10

=  4x + 3x - 10x - 6 - 10 = 0

=  4x -7x -16 = 0

=  3x - 16 = 0

= 3x = 16

By dividing 3 on both sides of equation:

= x = 16/3

= x = 5.333

                                                          x = 5.3333
