3х +7y = 2
— 3х - 2y = 8

(x,y)=(-4,2)

Step-by-step explanation:

{3х +7y = 2

{— 3х - 2y = 8

solve the equation for 3x

{3х = 2 -7y

{— 3х - 2y = 8

substitute the given value of 3x into the equation

-3x -2y=8

-(2-7y)-2y=8

solve the equation of y

y=2

substitute the given value of y into the equation

-3x -2x2=8

solve the equation for x

x=-4

the possible solution for the system is the ordered pair

(x,y)=(-4,2)

Check the given ordered pair is the solution of the system of equations

{3х (-4) + 7x2=2

{- 3х (-4) -2x2=8

simply the equalities

{2=2

{8=8

Sin e all the equalities are true ,the ordered pair is the solution of the system

(x,y)=(-4,2)

solution

(x,y)=(-4,2)

hope this .
