Explicație pas cu pas:
50x5+x÷10=260
250+x÷10=260
x÷10=260-250
x÷10=10
x=10x10=100
x=100
x÷5+56x5-380=220
x÷5+280-380=220
x÷5=220+380-280
x÷5=600-280
x÷5=320
x=320x5=1.600
x=1.600
50 × 5 + x : 10 = 260
250 + x : 10 = 260
x : 10 = 260 - 250
x : 10 = 10
x = 10 × 10
x = 100
X : 5 + 56 × 5 - 380 = 220
X : 5 + 280 - 380 = 220
X : 5 + 280 = 220 + 380
X : 5 + 280 = 600
X : 5 = 600 - 280
X : 5 = 320
X = 320 × 5
X = 1600
250 + x : 10 = 260
x : 10 = 260 - 250
x : 10 = 10
x = 10 × 10
x = 100
X : 5 + 56 × 5 - 380 = 220
X : 5 + 280 - 380 = 220
X : 5 + 280 = 220 + 380
X : 5 + 280 = 600
X : 5 = 600 - 280
X : 5 = 320
X = 320 × 5
X = 1600
