Question

Daca a : 6=9 si b:6=4 calculeaza suma si diferenta dintre a si b.

Answer 1

a : 6 = 9
a = 6 x 9 = 54
b : 6 = 4
b = 6 x 4 = 24
a + b = 54 + 24 = 78
a - b = 54 - 24 = 30

Answer 2

$x \div 6 = 9 \\ x = 9 \times 6 \\ x = 54 \\ \\ y \div 6 = 4 \\ y = 24 \\ x + y = 24 + 54 = 78 \\ x - y = 54 - 24 = 30$
