-3x-14-10x=19-2\left(2x-2\right)
Use the distributive property to multiply -2 by 7+5x.
-13x-14=19-2\left(2x-2\right)
Combine -3x and -10x to get -13x.
-13x-14=19-4x+4
Use the distributive property to multiply -2 by 2x-2.
-13x-14=23-4x
Add 19 and 4 to get 23.
-13x-14+4x=23
Add 4x to both sides.
-9x-14=23
Combine -13x and 4x to get -9x.
-9x=23+14
Add 14 to both sides.
-9x=37
Add 23 and 14 to get 37.
x=\frac{37}{-9}
Divide both sides by -9.
x=-\frac{37}{9}
Fraction \frac{37}{-9} can be rewritten as -\frac{37}{9} by extracting the negative sign.
