Question

what is the value of X for draw the graph of 3x + 7y = 27 , if y =3

a)2.
$b} \frac{20}{3}$
c) 9

$d} \frac{13}{3}$
​

Answer 1

Answer:

y = 3

3x + 7(3) = 27

3x + 21 = 27

3x = 27 -- 21

3x = 6

x = 6/3

x = 2

answer is 2

Answer 2

Answer:-

option a) 2

Explanation:-

if y = 3, substituting value of y in equation

⇒ 3x + 7y = 27

⇒ 3x + ( 7 × 3 ) = 27

⇒ 3x + 21 = 27

⇒ 3x = 27 - 21

⇒ 3x = 6

⇒ x =  $\frac{6}{3}$

                             x = 2
