Answer:
7
Explanation:
The value of b is 7.
6b+6=48
Carry over the 6 and make b the subject.
6b= 48-6
6b= 42
b= 42/6
b= 7
Therefore b=7
To find out if the answer is correct, replace the b with the value of what it is in brackets. Remember brackets mean to multiply.
6(7)+6= 48
42+6= 48
Therefore b=7 and the answer is correct.
