solve the substitution 3x+y=8 5x - 3y =4​

I think it's  {x,y} = {2,2}

Explanation:

x=2 and y=2

Explanation:

3x+y=8;5x−3y=4

Step: Solve3x+y=8for y:

3x+y=8

3x+y+−3x=8+−3x(Add -3x to both sides)

y=−3x+8

Step: Substitute−3x+8foryin5x−3y=4:

5x−3y=4

5x−3(−3x+8)=4

14x−24=4(Simplify both sides of the equation)

14x−24+24=4+24(Add 24 to both sides)

14x=28

14x

14

=

28

14

(Divide both sides by 14)

x=2

Step: Substitute2forxiny=−3x+8:

y=−3x+8

y=(−3)(2)+8

y=2(Simplify both sides of the equation)

x=2 and y=2
