Question

adrian si miruna au pictat pt craciun 10 postere adrian a pictat cu 2 postere mai mult decat mituna cate postere a pictat fiecare copil

Answer 1

A = Adrian

M = Miruna

A + M = 10

A = 2 + M

2 + M + M = 10

2 + 2 × M = 10

2 × M = 10 - 2

2 × M = 8

M = 8 : 2

M = 4

A = 2 + 4

A = 6

Answer 2

A=notăm pe Adrian

B=notăm pe Miruna

A+B=10

A=2+B

2+B+B=10

2+2×B=10

2×B=10-2

2×B=8

B=8:2

B=4

A=2+4

A=6
