Question

a x c= 200
a x (c+3) = 296

Answer 1

a×c = 200
a×(c+3) = 296
a×c+3a = 296
200+3a = 296
3a = 296-200
3a = 96
a = 96/3
a = 32.

a×c = 200
32c = 200
c = 200/32
c = 6,25.

Verificare : a×c = 32×6,25 = 200.



J'espère aidé :)

Answer 2

a x c= 200
a x (c+3) = 296
a×c+a×3=296
200 +a×3=296
a×3=296-200
a×3=96
a=96:3
a=32

a×c=200
32×c=200
c=200:32
c=6,25
