Question

Afla pe x din egalitatile de mai jos:
(x-14):14=24-10
(x+0).7=24.(6-6)
(17-14):(3-x)=12:12
x.0:7=10.(18-18)​

Answer 1

Rezolvare :

a)(x-14)÷14=24-10

(× -14)÷14 =14 / ×14

x -14 = 196

x = 210

b)(x+ 0) ×7 =24 ×(6-6)

(x +0 )×7 =24 ×0

(x+0) ×7 =0 /×7

x +0 = 0

x=0

c)(17-14) ÷ (3-x) =12 ×12

3 ÷ (3 - ×) = 144

3=144(3-x)

3= 432 - 144 x

144x = 432 -3

144x =429

x =2,97916

d)x×0÷7=10×(18-18)

0 =10 ×0

0 =0
