proszę o szybkie rozwiązanie. xD
Ale takie szybkie <3
Dam naj,;)

Answer 1

4x+1= x+10 |-x-1
3x=9|:3
x=3


5y+2=4y+3|-2-4y
y=1

6u=u+18|-u
5u=18|:5
u=3 i 3/5

9t+6=t+30|-t-6
8t=24|:8
t=3

9x+1=7x+19|-7x-1
2x=18|;2
x=9

5x+6=x+38|-x-6
4x=32|:4
x=8

3y+14=y+20|-y-14
2y=6|:2
y=3

2b+100=3b+50|-100-3b
-b=-50 |*(-1)
b=50

Answer 2

4x+1= x+10
4x-x=10-1
3x=9/3
x=3
5y+2=4y+3
5y-4y=3-2
y=1
6u=u+18
6u-u=18
5u=18/5
u=3⅗
9t+6=t+30
9t-t=30-6
8t=24/8
t=3
9x+1=7x+19
9x-7x=19-1
2x=18/2
x=9
5x+6=x+38
5x-x=38-6
4x=32/4
x=8
3y+14=y+20
3y-y=20-14
2y=6/2
y=3
2b+100=3b+50
2b-3b=50-100
-b=-50/(-1)
b=50

Answer 3

4x+1= x+10 /-1
4x = x + 9 / - x
3x = 9 /:3
x = 3

5y + 2= 4y + 3 /-4y
y+2=3 /-2
y = 1

6u =u+18
TEGO NIE WIEM :D

9t + 6= t + 30 /-6
9t = t+ 24 / -t
8t = 24 /:8
t = 3

9x + 1= 7x + 19 / -7x
2x + 1 = 19 / -1
2x = 18 / :2
x = 9

5x +6 = x +38 / -x
4x + 6 = 38 / -6
4x = 32 / :4
x = 8

3y +14 = y + 20 / - y
2y +14 = 20 / -14
2y = 6 /:2
y = 3

2b +100 = 3b +50 / 2b
100 = b + 50 /-50
50 = b
b= 50


Daj najj ;D
