3x\left(2-4\right)+2x-5\left(x+1\right)=\frac{-28}{2}
Divide both sides by 2.
3x\left(2-4\right)+2x-5\left(x+1\right)=-14
Divide -28 by 2 to get -14.
3x\left(-2\right)+2x-5\left(x+1\right)=-14
Subtract 4 from 2 to get -2.
-6x+2x-5\left(x+1\right)=-14
Multiply 3 and -2 to get -6.
-4x-5\left(x+1\right)=-14
Combine -6x and 2x to get -4x.
-4x-5x-5=-14
Use the distributive property to multiply -5 by x+1.
-9x-5=-14
Combine -4x and -5x to get -9x.
-9x=-14+5
Add 5 to both sides.
-9x=-9
Add -14 and 5 to get -9.
x=\frac{-9}{-9}
Divide both sides by -9.
x=1
Divide -9 by -9 to get 1.
