Question

Answer 1

let the no. be x
ATQ, 2x-7=25
2x=32
x=16

Answer 2

Hey!
_________________________________

Let the number be $\bf{x}$

$\large{\textsf{7 – 2x = 25}}$

$\large{\implies{\textsf{2x = 25 + 7}}}$

$\large{\implies{\textsf{2x = 32}}}$

Dividing both sides by 2, we have:

x = $\huge{\frac{32}{2} }$= $\large{\bold{\fbox{\red{ 16}}}}$

Verification:

$\large{\implies{\textsf{2*16 – 7 = 25}}}$

$\large{\implies{\textsf{32 – 7 = 25}}}$
