Answer:

x = -1

Step-by-step explanation:

[tex]10 - 7x - 5 + 12x = 0[/tex]

➡️ [tex]5 - 7x + 12x = 0[/tex]

➡️ [tex]5 + 5x = 0[/tex]

➡️ [tex]5 + 5x - 5 = 0 - 5[/tex]

➡️ [tex]5x = 0 - 5[/tex]

➡️ [tex]5x = - 5[/tex]

➡️ [tex]5x \div 5 = - 5 \div 5[/tex]

➡️ [tex]x = - 5 \div 5[/tex]

➡️ [tex]x = - 1[/tex]
