1+x<\frac{7}{3}\times \frac{-3}{2}
Divide 4 by 4 to get 1.
1+x<\frac{7}{3}\left(-\frac{3}{2}\right)
Fraction \frac{-3}{2} can be rewritten as -\frac{3}{2} by extracting the negative sign.
1+x<\frac{7\left(-3\right)}{3\times 2}
Multiply \frac{7}{3} times -\frac{3}{2} by multiplying numerator times numerator and denominator times denominator.
1+x<\frac{-21}{6}
Do the multiplications in the fraction \frac{7\left(-3\right)}{3\times 2}.
1+x<-\frac{7}{2}
Reduce the fraction \frac{-21}{6} to lowest terms by extracting and canceling out 3.
x<-\frac{7}{2}-1
Subtract 1 from both sides.
x<-\frac{7}{2}-\frac{2}{2}
Convert 1 to fraction \frac{2}{2}.
x<\frac{-7-2}{2}
Since -\frac{7}{2} and \frac{2}{2} have the same denominator, subtract them by subtracting their numerators.
x<-\frac{9}{2}
Subtract 2 from -7 to get -9.
