Question

Afla termenul necunoscut. [(a-200:5×4:5×4)×5+3]×2=726 pls​

Answer 1

Răspuns:

Explicație pas cu pas:

[(a-200÷5x4÷5x4)x5+3]x2=726

[(a-40x4÷20)x5+3]x2=726

[(a-160÷20)x5+3=726

[(a-8)x5+3]x2=726

[(a-8)x5+3]=726÷2

[(a-8)x5+3]=363

(a-8)x5=360-3

a-8=360÷5

a-8=72

a=72+8

a=80

Answer 2

[ ( a - 200 : 5 × 4 : 5 × 4 ) × 5 + 3 ] × 2 = 726

[ ( a - 40 × 4 : 5 × 4 ) × 5 + 3 ] × 2 = 726

[ ( a - 160 : 5 × 4 ) × 5 + 3 ] × 2 = 726

[ ( a - 32 × 4 ) × 5 + 3 ] × 2 = 726

[ ( a - 128 ) × 5 + 3 ] × 2 = 726

( a - 128 ) × 5 + 3 = 726 : 2

( a - 128 ) × 5 + 3 = 363

( a - 128 ) × 5 = 363 - 3

( a - 128 ) × 5 = 360

a - 128 = 360 : 5

a - 128 = 72

a = 72 + 128

a = 200
