Question

3x+2y=14
9x+6y=2
Solve by substitution method​

Answer 1

Answer:

3xy=14-2=12

xy=12/3

Xy=4

9xy=2-6=-4

xy=-4/9

Xy= -0.44444

Answer 2

Step-by-step explanation:

Firstly we require the value of anyone variable

3x=14-2y

x=(14-2y)/3 substitute this value in another equation.

so now,

9x+6y=2

$\frac{9(14 - 2y)}{3} + 6y = 2$

$42 - 6y + 6y = 2$

$42 > 2$

so here we can't find the value of variable.

so we can say that no value can satisfy both the equation.
