Answer 1

1) 3(х+3) - 3(4-х) - х - 3 = 3х + 9 - 12 + 3х - х - 3 = 5х - 6
2) 3(х+5) - (4-х) - (1+3)х - 3 = 3х + 15 - 4 + х - х - 3х - 3 = 8
3) 2 (х+4) - 3 (2-х) - х - 4 = 2х + 8 - 6 + 3х - х - 4 = 4х - 2
4) х + 1 - 5 (2-х) - (5+1)х - 5 = х + 1 - 10 + 5х - 5х -х - 5 = -14
5) х + 3 - (2-х) - х - 4 = х + 3 - 2 + х - х - 4 = х - 3
6) 4 (х+3) - (5-х) - х - 4 = 4х + 12 - 5 + х - х - 4 = 4х + 3
7) 3 (х+3) - 4 (х-1) - (4+3)х - 1 = 3х + 9 - 4х + 4 - 4х - 3х - 1 = 12 - 8х
8) 5 (х+5) - 3 (3-х) - х - 3 = 5х + 25 - 9 + 3х - х - 3 = 7х + 13
9) 2 (х+2) - 5 (2-х) - (5+2)х - 1 = 2х + 4 - 10 + 5х - 5х - 2х - 1 = -2
10) 2 (х+4) - 4 (5-х) - (4+2)х - 3 = 2х + 8 - 20 + 4х - 4х - 2х - 3 = -15

Answer 2

1) 3(x+3) - 3(4-x) - x - 3 = 3x + 9 - 12 + 3x - x - 3 = 5x - x - 6 = 4x - 6

2) 3(x+5) - (4-x) - (1+3)x - 3 = 3x + 15 - 4 + x - x - 3 = 3x + x + 8 - 4 = 4x + 4

3) 2(x+4) - 3(2-x) - x - 4 = 2x + 8 - 6 + 3x - x - 4 = 5x - x - 2 = 4x - 2

4) x + 1 - 5(2-x) - (5+1)x - 5 = x + 1 - 10 + 5x - 6 - 5x - 5 = x + 1 - 10 - 6 - 5 = x - 20

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

6) 4(x+3) - (5-x) - x - 4 = 4x + 12 - 5 + x - x - 4 = 4x + x + 3 - 4 = 5x - 1

7) 3(x+3) - 4(x-1) - (4+3)x - 1 = 3x + 9 - 4x + 4 - 7x - 1 = 3x - 4x - 7x + 9 + 4 - 1 = -8x + 12

8) 5(x+5) - 3(3-x) - x - 3 = 5x + 25 - 9 + 3x - x - 3 = 5x + 3x - x + 25 - 9 - 3 = 7x + 13

9) 2(x+2) - 5(2-x) - (5+2)x - 1 = 2x + 4 - 10 + 5x - 7x - 1 = 2x + 5x - 7x + 4 - 10 - 1 = 0x - 7

10) 2(x+4) - 4(5-x) - (4+2)x - 3 = 2x + 8 - 20 + 4x - 4x - 3 = 2x + 4x - 4x + 8 - 20 - 3 = 2x - 15
