Question

Afla valoarea lui x prin metoda mersului invers. 125+x-3210=10700, x-125+574=14302,294800-x+58=125000+75000, 478206+x-10+1000=470000.

Answer 1

125 + X - 3210 = 10700
125 + X = 10700 + 3210
125 + X = 13910
X = 13910 - 125
X = 13785.

X - 125 + 574 = 14302
X - 125 = 14302 - 574
X - 125 = 13728
X = 13728 + 125
X = 13853.

294800 - X + 58 = 125000 + 75000
294800 - X + 58 = 200000
294800 - X = 200000 - 58
294800 - X = 199942
X = 294800 - 199942
X = 94858.
