Rozwiąż Równania :

5x+2=8x+15

13y+1=7y+5

6y-1=9+y

Answer 1

A)5x+2=8x+15
5x-8x=15-2
-3x=13
-x=13/3
-x=4 1/3
x=-4 1/3

b)13y+1=7y+5
13y-7y=5-1
6y=4
y=4/6
y=2/3

c)6y-1=9+y
6y-y=9+1
5y=10
y=10/5
y=2

Answer 2

5x + 2 = 8x + 15
5x - 8x = 15 -2
- 3x = 13 / : (-3)
x = 13/3
x= - 4 i 1/3

13y+1 = 7y +5
13y - 7y = 5-1
6y = 4 / :6
y = 2/3


6y -1 = 9 + y
6y - y = 9+1
5y = 10 /:5
y= 2

Answer 3

5x+2=8x+15
5x-8x=15-2
-3x=13 /÷(-3)
x=13/(-3)
x=-4⅓

13y+1=7y+5
13y-7y=5-1
6y=4 /÷6
y=⁴/₆

6y-1=9+y
6y-y=9+1
5y=10 /÷5
y=2
