4-3x-7=20
To find the opposite of 3x+7, find the opposite of each term.
-3-3x=20
Subtract 7 from 4 to get -3.
-3x=20+3
Add 3 to both sides.
-3x=23
Add 20 and 3 to get 23.
x=\frac{23}{-3}
Divide both sides by -3.
x=-\frac{23}{3}
Fraction \frac{23}{-3} can be rewritten as -\frac{23}{3} by extracting the negative sign.
