If 8 times a number is increased by 3 the result is 19 more than 6 times this number find the number

8

Step-by-step explanation:

let x be the number

8*x+3=6*x+19

8x+3=6x+19

rearrange

8x-6x=19-3

2x=16

x=16/2=8

check: 8*8+3=64+3=67

            6*8+19=48+19=67

the y will be in still but your answer will be y x 3
