Question

Solve for x. km/3-2x=4

Answer 1

`(km)/(3)-2x=4\ \  \ \ |subtract\ (km)/(3)\ from\ both\ sides\\\\-2x=4-(km)/(3)\ \ \  \ \ |change\ signs\\\\2x=(km)/(3)-4\ \ \ \ \ |divide\ both\ sides\ by\ 2\ (multiply\ by\ (1)/(2))\\\\\boxed{x=(1)/(2)\left((km)/(3)-4\right)}\ \ \ \ |use\ distributive\ property:a(b-c)=ab-ac\\\\\boxed{x=(km)/(6)-2}`
