Question

se x = 1 -[6+(4-3-5) - (-9+6)] e y = (12+13) : (+5 - 30)-4 : (+3 - 7) - (- 4 - 8), caucule a) o valor de x;

b)o valor de y;

c)o valor de x - y

me ajudem pf

Answer 1

a)1-[6+(4-3-5)-(-9+6)]

1-[6+(1-5+15)]

1-[6+(-4+15)]

1-[6+11]

1-[17]

1-17=-16

b)(12+13)÷(+5-30)-4÷(+3-7)-(-4-8)

25÷(-25)-4÷(-4)-(-12)

-1-1+12

2+12=24

c)x-y

-16+24 = 40
