Answer:

x = 15

Step-by-step explanation:

create a proportion:   <u> x + 10 </u> = <u> x + x + 10 </u>

                                       5               8

cross-multiply:  8(x + 10) = 5(2x + 10)

                          8x + 80 = 10x + 50

                                  80 = 2x + 50

                                  30 = 2x

                                   15 = x

kobusy [5.1K]
