x+3(x+1)=47
x+3x+3=47
4x=47-3
4x=44
x=44/4
x=11 ans.
11+1=12 ans
Proof:
11+3*12=47
11+36=47
47=47

x is the first integer and x+1 is the next
By the question
x+3(x+1)=47
Distribute
x+3x+3=47
Combine the variables
4x+3=47
Subtract 3 from both sides
4x=44
Divide both sides by 4
x=44/4=11
If x=11 then x+1=12
Check
x+3(x+1)=11+3(12)=11+36=47
