-75x+300=5\left(14x-25\right)-200
Use the distributive property to multiply 3 by -25x+100.
-75x+300=70x-125-200
Use the distributive property to multiply 5 by 14x-25.
-75x+300=70x-325
Subtract 200 from -125 to get -325.
-75x+300-70x=-325
Subtract 70x from both sides.
-145x+300=-325
Combine -75x and -70x to get -145x.
-145x=-325-300
Subtract 300 from both sides.
-145x=-625
Subtract 300 from -325 to get -625.
x=\frac{-625}{-145}
Divide both sides by -145.
x=\frac{125}{29}
Reduce the fraction \frac{-625}{-145} to lowest terms by extracting and canceling out -5.
