Question

(x + 340) – 152 = 214
500 + (x + 140) = 2 056
800:y - 300 = 500
(a +200): 400 = 2​

Answer 1

Ответ:

x=26;

x=1416;

y=1;

a=600;

Пошаговое объяснение:

(x + 340) – 152 = 214

x+340=214+152

x=366-340

x=26

500 + (x + 140) = 2056

x+140=2056-500

x=2056-500-140

x=1416

800:y - 300 = 500

800:y=500+300

800:y=800

y=800/800

y=1

(a +200): 400 = 2

a+200=2*400

a=800-200

a=600
