Question

. Solve 3 x + 2y = 9 x - 4y = - 4​

Answer 1

Answer:

x=0.8 , y=0.8

Step-by-step explanation:

$3x + 2y = 9x - 4y = 4$

$3x + 2y = 9x - 4y \\ 2y + 4y = 9x - 3x \\ 6y = 6x \\ x = y$

$3x + 2y = 3x + 2x = 5x \\ 5x = - 4 \\ x = \frac{ - 4}{5} \\ x = - 0.8$

Answer 2

Answer:

x = 0.8 , y = 0.8

Step-by-step explanation:

Given

Solve 3 x + 2y = 9 x - 4y = - 4

To Find

Solve the Following ?

• 3 x + 2y = 9 x - 4y = - 4

Solution

$3x+2y=9x−4y=4$

$3x+2y=9x−4y$

$2y+4y=9x−3x6y \\ =6xx=y$

$3x+2y=3x+2x=5x$

$5x=−4x \\ =5−4x=−0.8$

Hence , Your Answer Is =

• x = 0.8
• y = 0.8
