Question

can you slove this for me ?

Answer 1

$6(2x + 5) = 5(3x - 6) \\ 12x + 30 = 15x - 30 \\ 12x + 30 - 15x + 30 = 0 \\ 5x + 60 = 0 \\ 5x = - 60 \\ x = - 12$

Answer 2

Answer:

• 20.

Step-by-step explanation:

$\rightarrow \bold{\dfrac{2x+5}{3x-6} =\dfrac{5}{6} }$

$\rightarrow \bold{6(2x+5)=5(3x-6)}$

$\rightarrow \bold{12x+30=15x-30}$

$\rightarrow \bold{12x-15x=-30-30}$

$\rightarrow \bold{-3x=-60}$

$\rightarrow \bold{x=\dfrac{-60}{-3}=20 }$

∴ Value of x is 20.

Verification:

$\rightarrow \bold{\dfrac{2x+5}{3x-6} =\dfrac{5}{6} }$

$\rightarrow \bold{6(2x+5)=5(3x-6)}$

$\rightarrow \bold{6(40+5)=5(60-6)}$

$\rightarrow \bold{6\times45=5\times54}$

$\rightarrow \bold{270=270}$

∴ L.H.S = R.H.S
