168+2x-15=20
Multiply 4 and 42 to get 168.
153+2x=20
Subtract 15 from 168 to get 153.
2x=20-153
Subtract 153 from both sides.
2x=-133
Subtract 153 from 20 to get -133.
x=\frac{-133}{2}
Divide both sides by 2.
x=-\frac{133}{2}
Fraction \frac{-133}{2} can be rewritten as -\frac{133}{2} by extracting the negative sign.
