Answer:
[tex]x = - \frac{25}{2} [/tex]
Alternative forms:
[tex]x = - 12 \frac{1}{2}, \: or \: x = - 12.5[/tex]
Step-by-step explanation:
[tex]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} [/tex]
