4-14x+21=3x-4\left(3x-5\right)
Use the distributive property to multiply -7 by 2x-3.
25-14x=3x-4\left(3x-5\right)
Add 4 and 21 to get 25.
25-14x=3x-12x+20
Use the distributive property to multiply -4 by 3x-5.
25-14x=-9x+20
Combine 3x and -12x to get -9x.
25-14x+9x=20
Add 9x to both sides.
25-5x=20
Combine -14x and 9x to get -5x.
-5x=20-25
Subtract 25 from both sides.
-5x=-5
Subtract 25 from 20 to get -5.
x=\frac{-5}{-5}
Divide both sides by -5.
x=1
Divide -5 by -5 to get 1.
