Question

reduce the following equations to their linear form and solver
r/2+1/3=r/5+1/4

Answer 1

Answer:

18r = -5

∴ r = $\frac{-5}{18}$

Step-by-step explanation:

$\frac{r}{2}$ + $\frac{1}{3}$ = $\frac{r}{5}$ + $\frac{1}{4}$

=> 30r + 20 = 12r + 15 [Multiplying both sides of the equation by 60]

=> 30r - 12r = 15 - 20

=> 18r = -5

∴ r = $\frac{-5}{18}$
