Question

помогите, дам 15 баллов.
a+23a=1032
16x-x+14=299
7b+6b-29=374
19y-12y-47=1388

Answer 1

1. a + 23a = 1032
24a = 1032
a = 1032 / 24
a = 43

2. 16x - x + 14 = 299
15x + 14 = 299
15x = 299 - 14
15x = 285
x = 285 / 15
x = 19

3. 7b + 6b - 29 = 374
13b - 29 = 374
13b = 374 + 29
13b = 403
b = 403 / 13
b = 31

4. 19y - 12y - 47 = 1388
7y - 47 = 1388
7y = 1388 + 47
7y = 1435
y = 1435 / 7
y = 205
