\frac{19}{18}x-\left(-\frac{1}{2}x-\frac{3}{2}x-1-\frac{1}{3}x\right)=-\left(\frac{4}{2}-2x\right)
To find the opposite of \frac{3}{2}x+1, find the opposite of each term.
\frac{19}{18}x-\left(-2x-1-\frac{1}{3}x\right)=-\left(\frac{4}{2}-2x\right)
Combine -\frac{1}{2}x and -\frac{3}{2}x to get -2x.
\frac{19}{18}x-\left(-\frac{7}{3}x-1\right)=-\left(\frac{4}{2}-2x\right)
Combine -2x and -\frac{1}{3}x to get -\frac{7}{3}x.
\frac{19}{18}x-\left(-\frac{7}{3}x\right)-\left(-1\right)=-\left(\frac{4}{2}-2x\right)
To find the opposite of -\frac{7}{3}x-1, find the opposite of each term.
\frac{19}{18}x+\frac{7}{3}x-\left(-1\right)=-\left(\frac{4}{2}-2x\right)
The opposite of -\frac{7}{3}x is \frac{7}{3}x.
\frac{19}{18}x+\frac{7}{3}x+1=-\left(\frac{4}{2}-2x\right)
The opposite of -1 is 1.
\frac{61}{18}x+1=-\left(\frac{4}{2}-2x\right)
Combine \frac{19}{18}x and \frac{7}{3}x to get \frac{61}{18}x.
\frac{61}{18}x+1=-\left(2-2x\right)
Divide 4 by 2 to get 2.
\frac{61}{18}x+1=-2-\left(-2x\right)
To find the opposite of 2-2x, find the opposite of each term.
\frac{61}{18}x+1=-2+2x
The opposite of -2x is 2x.
\frac{61}{18}x+1-2x=-2
Subtract 2x from both sides.
\frac{25}{18}x+1=-2
Combine \frac{61}{18}x and -2x to get \frac{25}{18}x.
\frac{25}{18}x=-2-1
Subtract 1 from both sides.
\frac{25}{18}x=-3
Subtract 1 from -2 to get -3.
x=-3\times \frac{18}{25}
Multiply both sides by \frac{18}{25}, the reciprocal of \frac{25}{18}.
x=\frac{-3\times 18}{25}
Express -3\times \frac{18}{25} as a single fraction.
x=\frac{-54}{25}
Multiply -3 and 18 to get -54.
x=-\frac{54}{25}
Fraction \frac{-54}{25} can be rewritten as -\frac{54}{25} by extracting the negative sign.
