Respuesta :

2x-3+7x-10=32
9x-13=32
9x=32+13
9x=45
x=5

The value of x is 5

Since point b is between points a and c

The equation below represents the given illustration

ab   +   bc    =   ac.................(*)

ab   =   2x  -  3

bc   =  7x  -  10

ac   =   32

Substituting the values of ab, bc, and ac into equation (*)

2x  -  3    +   7x   -  10    =   32

Collect like terms

2x   +  7x   =   32  +  10  +  3

9x    =   45

Divide both sides by 9

9x / 9    =   45/9

x     =   5
