Answer:

x=1 y=2, there are your answers. Have a good day

Explanation:

y=−3x+5;5x−4y=−3

Step: Solve: y=−3x+5for y:

Step: Substitute: −3x+5foryin5x−4y=−3:

5x−4y=−3

5x−4(−3x+5)=−3

17x−20=−3 (you have to simplify both sides of the equation)

17x−20+20=−3+20(then add 20 to both sides)

17x=17

17x

17

=

17

17

(Divide both sides by 17)

x=1

Step: Substitute1forxiny=−3x+5:

y=−3x+5

y=(−3)(1)+5

y=2( again Simplify both sides of the equation)

The Answer Is:

x=1 and y=2

Am I incorrect?
