Isolate s in first equation: Look at the first equation in the system.The first equation is −7=s+(−13). To find the value of s, we need to isolate s on one side of the equation.
Add 13 to isolate s: Add 13 to both sides of the first equation to isolate s.−7+13=s+(−13)+13This simplifies to:6=s
Substitute s into second equation: Substitute the value of s into the second equation to check for consistency.The second equation is simply s=, which means it is asking for the value of s. Since we have found that s=6 from the first equation, this is consistent with the second equation.
Conclude the solution: Conclude the solution.Since the value of s=6 satisfies both equations in the system, we have found the solution to the system.
