Could someone help me solves these questions? And can you show me how you did it? I can't figure out how to do these ones... I would really appreciate any help.
Questions~~
~ 3x – 19 = -2


~ 4x - 12x = 62 + 4(11)


~ x/8 + 7 = - 10


~ 4(5x – 9) = -2(3x + 7)


~ ½ x – 5 = (-3/8)x + 2


~ 3(x – 4) – (x + 5) = 2x + 11

  1. If you show us how you would do the first problem, we can help you with the others.

  2. 3x – 19 = -2
    Add ‘19’ to each side of the equation ~ -19+19+3x= -2+19

    Combine like terms~ -19+19=0
    0+3x= -2+19
    3x= -2+19

    Combine like terms~ -2+19=17
    3x=17

    Divide each side by‘3’~ x=5.666666667
    X = 5.666666667

  3. Good.

    What about the others?

  4. 2. 4x - 12x = 62 + 4(11)
    Combine like terms ~ 4x+-12x=-8x
    -8x= 62+4(11)
    Multiply ~ 4*11
    -8x=62+44
    Combine like terms ~ 62+44=106
    -8x=106
    Divide each side by ‘-8’ X=-13.25
    X= -13.25

    3. x/8 + 7 = - 10
    ?? I can't figure this out


    4. 4(5x – 9) = -2(3x + 7)
    Add ‘6x’to each side of the equation ~ -36+20x+6x= -14+ -6x+6x
    Combine like terms ~ 20x +6x=26x
    -36+26x=-14+ -6x+6x
    Combine like terms ~ -6x+6x=0
    -36+26x= -14+0
    -36+26=-14
    Add ‘36’ to each side of the equation ~ -36+36+26x=-14+36
    Combine like terms ~ -36+36=0
    0+26x= -14+36
    26x= -14+36
    Combine like terms ~ -14+36=22
    26x=22
    Divide each side by ‘26’ ~ x= 0.8461538462
    x= 0.8461538462

    5. ½ x – 5 = (-3/8)x + 2
    ?? I can't figure this one out

    6. 3(x – 4) – (x + 5) = 2x + 11
    Combine like terms ~ -12+ -5= -17
    -17+3x+ -1x=2x+11
    Combine like terms ~ 3x+ -1x=2x
    -17+2x=2x+11
    Add ‘-2x’ to each side of the equation
    -17+2x+-2x=11+2x+-2x
    Combine like terms~ 2x+ -2x=0
    -17+0=11+2x+-2x
    -17=11+2x+-2x
    Combine like terms~ 2x+ -2x=0
    -17+11+0
    -17=11


    Could you please show me how to do #3 and #5?
