63 :(5X - 3X - 1)=21:3

Crazy boy [7]

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.

What is the value of 9x^2 + 13x – 15, if x = 2

Paladinen [302]

Given,

$9 {x}^{2} + 13x - 15$
