What is the solution to the equation below?

-1 + 3x - 8 = 7

x=16/3

Step-by-step explanation:

left part : - 1+3x-8

right part: 7

left part = right part

-1+3x-8=7

left part + 8 = right part + 8

-1 + 3x - 8 + 8=7+8

-1+3x=15

left part : - 1+3x

right part : 15

left part+1=right part+1

-1+3x+1=15+1

3x=16

so

x=16/3
