    Answer:

    x =  -  \frac{25}{2}

    Alternative forms:

    x =  - 12 \frac{1}{2}</strong><strong>,</strong><strong> \: or \: x =  - 12.5

    Step-by-step explanation:

    4(2x - 10) = 12x + 10 \\ first \: you \: need \: to \: distribute \\  \\ 8x - 40 = 12x + 10 \\ subtract \: 12x \: from \: both \: sides \\  \\  - 4x - 40 = 10 \\ add \: 40 \: from \: both \: sides \\  \\  - 4x = 50 \\ divide \: both \: sides \: by \:  - 4 \\  \\ x =  -  \frac{25}{2}
