3-1,4-\left(-x\right)+5x=-\left(x-4,8\right)
To find the opposite of 1,4-x, find the opposite of each term.
3-1,4+x+5x=-\left(x-4,8\right)
The opposite of -x is x.
1,6+x+5x=-\left(x-4,8\right)
Subtract 1,4 from 3 to get 1,6.
1,6+6x=-\left(x-4,8\right)
Combine x and 5x to get 6x.
1,6+6x=-x-\left(-4,8\right)
To find the opposite of x-4,8, find the opposite of each term.
1,6+6x=-x+4,8
The opposite of -4,8 is 4,8.
1,6+6x+x=4,8
Add x to both sides.
1,6+7x=4,8
Combine 6x and x to get 7x.
7x=4,8-1,6
Subtract 1,6 from both sides.
7x=3,2
Subtract 1,6 from 4,8 to get 3,2.
x=\frac{3,2}{7}
Divide both sides by 7.
x=\frac{32}{70}
Expand \frac{3,2}{7} by multiplying both numerator and the denominator by 10.
x=\frac{16}{35}
Reduce the fraction \frac{32}{70} to lowest terms by extracting and canceling out 2.
