What is 7 (4j + 1 + 9j) as a verbal expression?

To find j:

First you need to add 4j and 9j

7 (4j + 1 + 9j)

= 7 (13j + 1)

Then you have to multiply 7 by the parenthesis

7 (13j + 1)

= 91j + 7

You need now to transfer 7 to the other side of the equal and 7 become the opposite

91j + 7

91j = - 7

now we have to isolate the j so you need to divide by 91 the two sides

91j = - 7

j = - 1/13

if you want to find the answer that gives an integer, replace j with the result found and make the equation

7 (4j + 1 + 9j)

7[4 (-1/13) + 1 + 9 (-1/13) ]

7 (-4/13 + 1 - 9/13)

7 (0)

= 0
