Question

Dacă x-17x4=y x8=z:2:3=56:u=8 atunci x+y-z+u=

Answer 1

x - 17×4 = y × 8 = z : 2 : 3 = 56 : u = 8

56 : u = 8
u = 56 : 8 = 7

z : 2 : 3 = 8
z : 2 = 24
z = 48

y × 8 = 8
y = 8:8
y = 1

x - 17×4 = 8
x - 68 = 8
x = 8+68
x = 76

x + y - z + u =
= 76 + 1 - 48 + 7 =
= 77 - 48 + 7 =
= 36

Answer 2

x-17×4=8
x=8+68
x=76
y×8=8
y=8:8
y=1
z:2:3=8
z:2=24
z=24×2
z=48
56:u=8
u=56:8
u=7
x+y-z+u=76+1-48+7=77-48+7=
29+7=36
