Answer 1

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

2x - 6 - 3x = 5

-x = 11

x = -11

2) 1 - 3(2 - x) = 4

1 - 6 + 3x = 4

3x = 4 - 1 + 6

3x = 9

x = 9/3

x = 3

3) x + 7 = 11(x + 2)

x = 11x + 22 - 7

x - 11x = 15

-10x = 15

10x = -15

x = - 15/10

x = -1,5

4) -7 - 6x = 3 - (2 + 5x)

-6x = 3 - 2 - 5x + 7

-6x + 5x = 1 + 7

-x = 8

x = -8

5) 4(x + 5) - 3(7 - 2x) = 0

4x + 20 - 21 + 6x = 0

10x = 21 - 20

10x = 1

x = 1/10

x = 0,1

Answer 2

1. 2(x-3)=3x+5
2x-6-3x-5=0
-x=11
x=-11
2. 1-3(2-x)=4
1-6+3x-4=0
3x=9
x=3
3. x+7=11(x+2)
x+7=11x+22
-10x=15
x=2/3
4. -7-6x=3-(2+5x)
-7-6x=3-2-5x
-x=9
x=-9
5. 4(x+5)-3(7-2x)=0
4x+20-21+6x=0
10x=1
x=0,1
