If 4 : 9 is equivalent to (5x+13) : 63, then what is the value of x?

Aleksandr [31]

$\large{\underline{\underline{\pmb{\sf{\color{yellow}{Answer:}}}}}}$

The value of x is 3

Step-by-step explanation:

$\textsf{\underline{\large{To find :-}}}$

The value of x

$\textsf{\underline{\large{Given :-}}}$

4 : 9 = (5x + 13) : 63

$\textsf{\underline{\underline{\large{Solution :-}}}}$

we can write this as

$\sf \frac{4}{9} = \frac{(5x + 13)}{63}$

Now we will cross multiply the values

$\sf 4 \times 63 = 9(5x + 13) \\ \\ \sf 252 = 45x + 117 \\ \\ \sf 252 - 117 = 45x \\ \\ \sf 135 = 45x \\ \\ \sf \frac{135}{45} = x \\ \\ \sf \orange {3 = x}$
