Isolate j in first equation: Look at the first equation in the system.The first equation is j+1=10.To find the value of j, we need to isolate j on one side of the equation.Subtract 1 from both sides of the equation to solve for j.j+1−1=10−1j=9
Substitute j into second equation: Substitute the value of j into the second equation to check for consistency.The second equation is j=□.Since we found that j=9 from the first equation, we substitute 9 into the second equation.9=□This is not a standard equation, but it seems to imply that the value of j should be placed in the box.Since we have found j to be 9, we would place 9 in the box.
Verify solution for both equations: Verify that the solution satisfies both equations in the system.The first equation is satisfied because j+1=9+1=10, which is true.The second equation is not a standard algebraic equation, but since it indicates that j should equal the value in the box, and we have determined j to be 9, it is also satisfied.
