3- 2x-(x-1)=5-(x-3)
4- 2(x+1)-3(2x-5)=6x
5- 4y=30-18
6-8x-43=65
7- 23x-16=14-17x
8- x-(2x-1)=23
9- 5z-6=z+14
10- m+4=20​

Answer 1

3) 2x-(x-1)=5-(x-3)

2x-x+1 = 5-x+3

2x-x+x = 5+3-1

2x = 7

x = 7/2

4) 2(x+1)-3(2x-5)=6x

2x+2-6x+15 = 6x

2x-6x-6x = -2-15

-10x = -17

x = 17/10

5) 4y=30-18

4y = 12

y = 12/4

y = 3

6) 8x-43=65

7x = 65+43

7x = 108

x = 108/7

7) 23x-16=14-17x

23x+17x = 14+16

40x = 30

x = 30/40

x = 3/4

8) x-(2x-1)=23

x-2x+1 = 23

x-2x = 23-1

-x = 22

x = -22

9) 5z-6=z+14

5z-z = 14+6

4z = 20

z = 20/4

z = 5

10) m+4=20

m = 20-4

m = 16
