1. 4x-15x+2.5=21-9x

4x-15x+9x=21-2.5

-2x=18.5

x=-9.25

2. 3x-4.5+2x=12.5-10x

3x+2x+10x=12.5+4.5

15x=17

x=17/15

3. 18x-3-12x-4=3

18x-12x=3+3+4

6x=10

x=10/6

4. 2x-6+3+6x=1

2x+6x=1+6-3

8x=4

x=0.5

1. 4x - 5 (3x-0.5) = 3 (7-3x)2. 3 (x - 1.5) + 2x = 5 (2.5 - 2x)3. 3 (6x-1) - 4 (3x+1) = 34. 2 (x-3) + 3 (1+2 x) = 1

1. 4x - 5 (3x-0.5) = 3 (7-3x)

2. 3 (x - 1.5) + 2x = 5 (2.5 - 2x)

3. 3 (6x-1) - 4 (3x+1) = 3

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