Question

7x +7y =0 and 3x-2y=10 elimination​

Answer 1

$\huge \bold{hey \: there}$

7x+7y=0---------(1)

3x-2y=10---------(2)

Multiplying equation (1) by 3 and (2) by 7,

➡21x+21y=0------(3)

➡21x-14y=70------(4)

Subtracting (4) from (3),

➡35y=-70

➡y=-2

Substituting this value in (1),

➡7x+7(-2)=0

➡7x-14=0

➡7x=14

➡x=2

Hence, x=2 and y=-2.
