Question

a. (x × 3 + 47) - 315 = 146
b. (x: 6 - 528) + 307 = 517
c. (x:3-3) × 9 = 306
d. (x: 2) × 3 = 30 × 3
e. (7 9 - x ×5) - 27:9 = 20
f. 909: 9 - (9 × 9:x-9) = 101
g. 35 x 5 - 54: x x 4 = 139
h. 60 - 10:(37 - 4 × x) = 50
i. 81 +9:9 x (x + 7) = 101
î.38 + (38 +x: 3) - 3 x 10 = 84
va rog rapidd!​

Answer 1

Răspuns:

a. 3x+47-315=146

3x+47=146+315

3x+47=461

3x=461-47

3x=414

x=414:3

x=138

b.(x:6-528)+307=415

(x:6-528)=415-307

(x:6-528)=108

x:6=108+528

x:6=636

x=6*636

x=3816

c.(x:3-3)*9=306

x:3-3=306:9

x:3-3=34

x:3=34-3

x:3=31

3x=31x3

3x=93

x=93:3

x=31
