Question

7 (n+4) = 21
Please help me solve this

Answer 1

Answer: n = -1

Step-by-step explanation: distribute 7 to n +4 to get 7n +28 = 21

subtract 28 on both sides, to get 7n= -7 divide by positive 7, and get n=-1

plug it in to check 7(-1+4)=21

-1+4= 3

7(3)= 21

it checks out ^_^

Answer 2

Answer is n= -1 Explanation first thing you need to do is to divide the 7 and 21 to get n+4=3. After that move the constant 4 and switch it with 3. N+3=4. Then calculate n+3=4 to get n= -1
