x+\frac{5}{2}-5x=-\frac{7}{4}
Subtract 5x from both sides.
-4x+\frac{5}{2}=-\frac{7}{4}
Combine x and -5x to get -4x.
-4x=-\frac{7}{4}-\frac{5}{2}
Subtract \frac{5}{2} from both sides.
-4x=-\frac{7}{4}-\frac{10}{4}
Least common multiple of 4 and 2 is 4. Convert -\frac{7}{4} and \frac{5}{2} to fractions with denominator 4.
-4x=\frac{-7-10}{4}
Since -\frac{7}{4} and \frac{10}{4} have the same denominator, subtract them by subtracting their numerators.
-4x=-\frac{17}{4}
Subtract 10 from -7 to get -17.
x=\frac{-\frac{17}{4}}{-4}
Divide both sides by -4.
x=\frac{-17}{4\left(-4\right)}
Express \frac{-\frac{17}{4}}{-4} as a single fraction.
x=\frac{-17}{-16}
Multiply 4 and -4 to get -16.
x=\frac{17}{16}
Fraction \frac{-17}{-16} can be simplified to \frac{17}{16} by removing the negative sign from both the numerator and the denominator.
