I’m thinking of a number. if you multiply it by 6 and then add 7 , you will get 55. what is my number

Let's call the unknown number . Based on the information, we can say:

If we subtract 7 from both sides, we get:

When you divide both sides of the equation by 6, we can isolate :

The number is 8.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
