Full solution

Q. Solve for jj.\newlinej+1=10 j+1= 10\newline j=j= \square
  1. Isolate jj in first equation: Look at the first equation in the system.\newlineThe first equation is j+1=10j + 1 = 10.\newlineTo find the value of jj, we need to isolate jj on one side of the equation.\newlineSubtract 11 from both sides of the equation to solve for jj.\newlinej+11=101j + 1 - 1 = 10 - 1\newlinej=9j = 9
  2. Substitute jj into second equation: Substitute the value of jj into the second equation to check for consistency.\newlineThe second equation is j=j = \square.\newlineSince we found that j=9j = 9 from the first equation, we substitute 99 into the second equation.\newline9=9 = \square\newlineThis is not a standard equation, but it seems to imply that the value of jj should be placed in the box.\newlineSince we have found jj to be 99, we would place 99 in the box.
  3. Verify solution for both equations: Verify that the solution satisfies both equations in the system.\newlineThe first equation is satisfied because j+1=9+1=10j + 1 = 9 + 1 = 10, which is true.\newlineThe second equation is not a standard algebraic equation, but since it indicates that jj should equal the value in the box, and we have determined jj to be 99, it is also satisfied.
