\frac{2}{3}-2x-5x=4
Subtract 5x from both sides.
\frac{2}{3}-7x=4
Combine -2x and -5x to get -7x.
-7x=4-\frac{2}{3}
Subtract \frac{2}{3} from both sides.
-7x=\frac{12}{3}-\frac{2}{3}
Convert 4 to fraction \frac{12}{3}.
-7x=\frac{12-2}{3}
Since \frac{12}{3} and \frac{2}{3} have the same denominator, subtract them by subtracting their numerators.
-7x=\frac{10}{3}
Subtract 2 from 12 to get 10.
x=\frac{\frac{10}{3}}{-7}
Divide both sides by -7.
x=\frac{10}{3\left(-7\right)}
Express \frac{\frac{10}{3}}{-7} as a single fraction.
x=\frac{10}{-21}
Multiply 3 and -7 to get -21.
x=-\frac{10}{21}
Fraction \frac{10}{-21} can be rewritten as -\frac{10}{21} by extracting the negative sign.
