Question

Fie ca (a+b+c+d):2=124.Află suma celor 4 numere dacă adunam câte 2 unitați la fiecare număr. URGENTTT

Answer 1

( a + b + c + d) : 2 = 124

a + b + c + d = 124 × 2

a + b + c + d = 248

( a + 2) + ( b + 2 ) + ( c + 2) + ( d + 2) = 248 + 8 → se mareste suma lor cu 8

a + b + c + d + 8 = 248 + 4 × 2

a + b + c + d + 8= 248 + 8

a + b + c + d + 8 = 256

Answer 2

( a + b + c + d)/2 =124

a + b + c + d = 124 × 2

a + b + c + d = 248

( a + 2) + ( b + 2 ) + ( c + 2) + ( d + 2) = 248 + 8

a + b + c + d + 8 = 248 + 4 × 2

a + b + c + d + 8= 248 + 8

a + b + c + d + 8 = 256
