224+30=75x\left(-4\right)+25
Multiply 56 and 4 to get 224.
254=75x\left(-4\right)+25
Add 224 and 30 to get 254.
254=-300x+25
Multiply 75 and -4 to get -300.
-300x+25=254
Swap sides so that all variable terms are on the left hand side.
-300x=254-25
Subtract 25 from both sides.
-300x=229
Subtract 25 from 254 to get 229.
x=\frac{229}{-300}
Divide both sides by -300.
x=-\frac{229}{300}
Fraction \frac{229}{-300} can be rewritten as -\frac{229}{300} by extracting the negative sign.
