Answer:

x = -1

Explanation:


10 - 7x - 5 + 12x = 0

➡️
5 - 7x + 12x = 0

➡️
5 + 5x = 0

➡️
5 + 5x - 5 = 0 - 5

➡️
5x = 0 - 5

➡️
5x = - 5

➡️
5x / 5 = - 5 / 5

➡️
x = - 5 / 5

➡️
x = - 1

10-7x-5+12x=0 Combine like terms
10-5 is 5 and -7x+12x is 5x so that makes
5x+5=0 Subtract 5 from both sides
5x=-5 Divide both sides by 5
x=-1
