Question

3x+2y;2x-y=1 solve in linear equations
​

Answer 1

Step-by-step explanation:

$3x + 2y = 0 \: \: \: equation \: 1\\ 2x - y = 1 \: \: \: \: \: \:equation \: 2 \\ multiply \: \: 3\: \: eq \: 1 \: and \: \: eq \: 2 \: \times 3 \\ 6x + 4y = 2 \\ 6x - 3y =3 \\ 0 + 7y \: \: = - 1 \\ \\ \: \: \: \: 7y = - 1 \\ y = - 1$

7y=-1

y=-1/7

substitude y value in equation 1

3x+2y=0

3x+2 (-1/7)=0

3×-2/7=0

3x=2/7

x=2/7×3

x=6/7
