Let the width be x.
Length = 5 + x
Perimeter = 58
2(l + w) = 58
2(5 + x + x) = 58
2(5 + 2x) = 58
10 + 4x = 58
4x = 48
x = 12
Hence, the length is 17 cm and the width is 12 cm.
As we can see here any negative number subtracting another negative number leads to adding. So we would have -6+2 which would be -4. So therefore your answer is -4
Answer:

Step-by-step explanation:
Solve by substitution. Solve the second equation for x:

Insert the value of x into the first equation:

Solve for y. Simplify multiplication using the distributive property:

Subtract 190 from both sides:

Isolate the variable to find its value. Divide both sides by -29:

Now take the value of y and insert back into either equation to solve for x:

Subtract 6 from both sides:

Divide both sides by 5:

Therefore, the solution to the system is
