63 :(5X - 3X - 1)=21:3​

Mathematics
1 answer:
Crazy boy [7]3 years ago

Answer:

x = 5

Step-by-step explanation:

Given that,

63:(5x-3x-1)=21:3\\\\or\\\\\dfrac{63}{(5x-3x-1)}=\dfrac{21}{3}\\\\\dfrac{63}{(2x-1)}=7

Cross multiplying both sides,

63=7(2x-1)\\\\9=2x-1

Taking like terms together,

10=2x\\\\x=5

So, the value of x is equal to 5.

I just need the answer no explanation
Eva8 [605]

Applying log rules leaves us with the following equation:

x^2 + 8 = 6x

Change to standard form and solve using factoring.

x^2 - 6x + 8 = 0

(x - 4)(x - 2) = 0

x = 4

x = 2

Hope this helps!
