Реши уравнения.
1) 3x + 7 = 13 2) 4t - 9 = 11 3) 13 + 5x = 63
32 - t = -1 2 (x + 5) = 16 4 (t + 7) = 40
x - 27 = -17 2 (x - 8) = 6 12 - 2x = 6

a1703 3х+7=13
3х=13-7
3х=6
х=6/3
x=2

4t - 9 = 11
4t = 11+9
4t=20
t=20/4
t=5

13 + 5x = 63
5x=63-13
5x=50
x=50/5
x=10

32 - t = -1
t=32+1
t=33

2 (x + 5) = 16
2x+10=16
2x=16-10
2x=6
x=6/2
x=3

4 (t + 7) = 40
4t+28=40
4t=40-28
4t=12
t=12/4
t=3

x - 27 = -17
x=27-17
x=10

2 (x - 8) = 6
2x-16=6
2x=6+16
2x=22
x=11

12 - 2x = 6
2x=12-6
2x=6
x=6/2
x=3
