Question

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

Answer 1

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
