Solve for x: -5/6x= -10/3 x=?
k0ka [10]

Answer:

Solve for x: -5/6x= -10/3 x=?

x = 1/4

Step-by-step explanation:

from the equation ,Solve for x: -5/6x= -10/3 , to solve for x  we will first cross multiply

we have; -15= -60x

divide both sides by -60

-15/-60 = -60x/-60

x = 15/60 ( the minus will cancel out)

x = 1/4

check for your answer  by putting 1/4 where you see x

i.e -5/6(1/4) = -10/3

-5 × 2/3 = -10/3

-10/3 = -10/3......... proved!!

\frac{r}{4}  = 10  -  2

\frac{r}{4}  = 8

r = 8 \times 2

r = 32
