7x+28-2\left(x-3\left(5+x\right)\right)=\frac{2}{3}\left(x-6\right)
Use the distributive property to multiply 7 by x+4.
7x+28-2\left(x-15-3x\right)=\frac{2}{3}\left(x-6\right)
Use the distributive property to multiply -3 by 5+x.
7x+28-2\left(-2x-15\right)=\frac{2}{3}\left(x-6\right)
Combine x and -3x to get -2x.
7x+28+4x+30=\frac{2}{3}\left(x-6\right)
Use the distributive property to multiply -2 by -2x-15.
11x+28+30=\frac{2}{3}\left(x-6\right)
Combine 7x and 4x to get 11x.
11x+58=\frac{2}{3}\left(x-6\right)
Add 28 and 30 to get 58.
11x+58=\frac{2}{3}x+\frac{2}{3}\left(-6\right)
Use the distributive property to multiply \frac{2}{3} by x-6.
11x+58=\frac{2}{3}x+\frac{2\left(-6\right)}{3}
Express \frac{2}{3}\left(-6\right) as a single fraction.
11x+58=\frac{2}{3}x+\frac{-12}{3}
Multiply 2 and -6 to get -12.
11x+58=\frac{2}{3}x-4
Divide -12 by 3 to get -4.
11x+58-\frac{2}{3}x=-4
Subtract \frac{2}{3}x from both sides.
\frac{31}{3}x+58=-4
Combine 11x and -\frac{2}{3}x to get \frac{31}{3}x.
\frac{31}{3}x=-4-58
Subtract 58 from both sides.
\frac{31}{3}x=-62
Subtract 58 from -4 to get -62.
x=-62\times \frac{3}{31}
Multiply both sides by \frac{3}{31}, the reciprocal of \frac{31}{3}.
x=\frac{-62\times 3}{31}
Express -62\times \frac{3}{31} as a single fraction.
x=\frac{-186}{31}
Multiply -62 and 3 to get -186.
x=-6
Divide -186 by 31 to get -6.
