Question

If x =2/3y and y = 18, what is the value of 2x - 3

Answer 1

2/3(18)
=12

x=12

2x-3
2(12)-3
24-3
21

Answer 2

Answer:

$2x-3=21$ when x=12.

Step-by-step explanation:

Given : If $x=\frac{2}{3}y$ and $y=18$

To find : The value of $2x-3$?

Solution :

The expression given as $x=\frac{2}{3}y$

Substitute the value of $y=18$

$x=\frac{2}{3}\times (18)$

$x=2\times6$

$x=12$

So, The value of x is 12.

Substitute x in $2x-3$,

$=2(12)-3$

$=24-3$

$=21$

Therefore, $2x-3=21$ when x=12.
