The answer is
nearest one: 3
It will be 9x + 1 = 12x + 20.
The answer you’ll put in the box is 1, because it doesn’t ask you to solve for x, just fill in the number.
2/3x-1/5=x-1
Add similar elements 23x-15=8x
Subtract x from both sides 8x-x=x-1-x
Simply 7x=-x
Divide both sides by 7 7x = -1
__ __. *Simply: x=-1/7
7 7
