Question

afla nr necunoscute 538-x+821=1798 x+4281+3584=30000 2030+x-13521=8213 va rog daca se poate repede

Answer 1

538 - x + 821 = 1798
- x = - 538 - 821 + 1798
-x = - 1359 + 1798
x = - 439
x + 4281 + 3584 = 30000
x = 30000 - 4281 - 3584
x = 22135
2030 + x - 13521 = 8213
x = 8213 - 2030 + 13521
x = 19704

Answer 2

538-x+821=1798
1359-x=1798
x=1359-1798
x=-439

x+4281+3584=30000
x+7865=30000
x=30000-7865
x=22135

2030+x-13521=8213
x-11491=8213
x=8213+11491
x=19704
