Question

1. Solve 4n = 24
2. Solve 2(t+ 8) = 22
3. Solve 3x + 3 = 2x + 9
4. Solve 2t - 7 = 3
5. Solve 2a - 3 = 24 - a

Answer 1

Ответ:

Пошаговое объяснение:

4n = 24

n=24:4

n= 6

2(t+ 8) = 22

t+8=22:2

t+8=11

t=11-8

t=3

3x + 3 = 2x + 9

3x -2x=9-3

x=6

2t - 7 = 3

2t=3+7

2t=10

t=10:2

t=5

2a - 3 = 24 - a

2a+a=24+3

3a=27

a=27:3

a=9
