 10(a+b) + (a+b) = 143

 i cant understand it now also!

Oops!sorry Melody i just wrote the incorrect name , ive just corrected it!Thanks for reminding me!i think in the tension of tomorrows exam i am not doing anything correctly!

okay okay!i think i had just messed it all up!i just used a silly shortcut which had put me in trouble!thank you Alan for clearing out my doubt!i think today you'll be earning a lot of points from me!

okay so the formula i wrote was correct!

Thank you Alan!I'll give u points for your answers!

so we would do the rest like

2x + 20/15 = 62/15

2x = 62/15 - 20/15

2x= 42/15

x=42/15 ÷ 2

x = 42/15 * 1/2

x=21/15 

x=7/5

x= 1 2/5     ANSWER

Thank you Alan for helping me!Just one thing to ask!

Whats the perimeter of an isosceles triangle!i mean whats its formula?

Is it 

P=b + s + s
