let four consecutive numbers are x,x+1,x+2,x+3
condition:
x+(x+1)+(x+2)+1=2(x+3)
3x+4=2x+6
3x-2x=6-4
x=2
Now first number 2
2nd number=x+1
2nd number=2+1=3
3rd number=x+2
3rd number=2+2=4
4th number=x+3
4th number=2+3=5

Step-by-step explanation:
Step one:
charges per hour= $60
We are told that the electrician earned $350
for a job that took 5hours
The linear equation to represent his earnings is
let the flat fee be x
C=60t+x------------1
so for C=$350
Required
the flat fee
350=60(5)+x
350=300+x
collect like terms
x=350-300
x=50
Flat fee is $50
