Question

aflati valorile nr x: x-126=904-492; x+128=917-208; 705-x=613-251; 425+x=823-131

Answer 1

x - 126 = 904 - 492

x - 126 = 412 .

x = 412 + 126

x = 538


x + 128 = 917 - 208

x + 128 = 709

x = 709 - 128

x = 581


705 - x = 613 - 251

705 - x = 362

x = 705 - 362

x = 343


425 + x = 823 - 131

425 + x = 692

x = 692 - 425

x = 267

Answer 2

Explicație pas cu pas:

1. x-126=904-492;

x-126=412

x=412+126=538

2. x+128=917-208;

x+128=709

x=709-128=581

3. 705-x=613-251;

705-x=362

x=705-362=343

4. 425+x=823-131

425+x=692

x=692-425=267
