Answer 2

hi,
here is your solution..
~~~~~~~~~~~~~~~~~~~

first,
we have to find out the value of "x".

==>7x + 4 = 25
==>7x = 25 - 4
==>7x = 21
==> x = 21/7
==> x = 3

so, the value of x is 3


now, the value of 2x + 3:--

==>2x + 3
==>2(3) + 3 [ x = 3 ]
==>6 + 3
==>9

so, the value of 2x + 3 is 9
