Answer:
Usually there are the variables x y z but it doesn't matter what they are.
Step-by-step explanation:
First choose your first variable to solve. Find x by putting all the numbers and variables to one side.
once you found x substitute the answer for x in all the equations. Next find y and substitute your answer in all the equations again.
Once you have solved 2 variables then you are able to solve z.

3. Answer: a) RT
b) XZ
c) TS
4. Answer: a) 26
b) 58
c) 21.5
d) 127
<u>Step-by-step explanation:</u>
2(PT) = AE 2(CP) = AN 2(CT) = EN
2(13) = AE 2(29) = AN 2(CT) = 43
26 = AE 58 = AN CT = 21.5
Perimeter = AE + AN + EN
= 26 + 58 + 43
= 127
