Question

[(624+123:3-a):6]x3+254=554 dau coroana!!
​

Answer 1

[(624+123:3-a):6]×3+254=554

[(624+41-a):6]×3+254=554

[(665-a):6]×3+254=554

665-a+508=1108

1173-a=1108

-a=-65 => a=65

Answer 2

Răspuns:

Explicație pas cu pas:

[(624+123:3-a):6]x3+254=554

[(624+ 41-a):6]x3 = 554 - 254

[(665 - a ) : 6 ]x3 = 300

(665 - a ) : 6 = 300 : 3

(665 - a ) : 6 = 100

665 - a = 100 × 6

665 - a = 600

a = 665 - 600

a = 65
