help help, ajutati-ma pls




$463 - a + 11 = 210$
$9 \times a + 14 = 86$
​

Answer 1

Răspuns:

463 - a + 11 = 210

463 - a = 210 - 11

463 - a = 199

a = 463 - 199

a = 264

9 × a + 14 = 86

9 × a = 86 - 14

9 × a = 72

a = 72 : 9

a = 8

Answer 2

463-a+11=210

463+11-a=210

474-a=210

-a=210-474

-a=-264

a=264

9×a+14=86

9×a=86-14

9×a=72

a=72:9

a=8
