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
