Answer:
20c+14
Step-by-step explanation:
To find the perimeter we have to add up all the sides
4c+6c+7+4c+6c+7
Combine light terms
20c+14

so if x = -1, let's plug that in the second equation
-5(-1)+y = 5
5+y = 5
y = 0
10 more than (+) twice a number (2x) is (=) 36
10 + 2x = 36 Subtract 10 from both sides
2x = 26 Divide both sides by 2
x = 13
