Answer:
7
Step-by-step explanation:
3x+6 = 27
Carry over the 6 to the 27 and make x the subject.
3x= 27-6
3x= 21
x= 21/3
x= 7
To check if the answer was correct, replace the x with the value it is in brackets. Remember brackets mean to multiply. The value of x is 7.
3(7)+6= 27
21+6= 27
Therefore the answer is correct and x= 7
