Question

-4=-2/3u solve for U

Answer 1

u = 6

Explanation:

`-(2)/(3)u=-4\qquad\text{change the signs}\\\\(2)/(3)u=4\qquad\text{multiply both sides by}\ (3)/(2)\\\\(3\!\!\!\!\diagup^1)/(2\!\!\!\!\diagup_1)\cdot(2\!\!\!\!\diagup^1)/(3\!\!\!\!\diagup_1)u=4\!\!\!\!\diagup^2\cdot(3)/(2\!\!\!\!\diagup_1)\\\\u=(2)(3)\\\\u=6`
