Respuesta :

Answer:

Step-by-step explanation:

a+b=83

a=83-b_____1

2a+3b=203

2a=203-3b

a=203-3b/2_____2

1-2=0

so.....

83-b-(203-3b)/2=0

83-b+(-203+3b)/2=0

83-b-101.5+1.5b=0

83-101.5-b+1.5b=0

-18.5+1/2b=0

b=-18.5*2= -37

so.........

we know thaaaaat -37+A =83

SO A=83+37=120

I THINK I DID IT CORRECTLY,ANYWAY CHECK IT YOURSELF IF IT IS CORRECT PLZ MARK ME AS  BRAINLIEST
