y=5x+23, -2x-y=5 i need help with this, it’s solving by substitution. i don’t get it someone pls help

if this doesn't help u let me know and i can explain more have a good day <3

x=−4 and y=3

Step-by-step explanation:

Step: Solvey=5x+23for y:

y=5x+23

Step: Substitute5x+23foryin−2x−y=5:

−2x−y=5

−2x−(5x+23)=5

−7x−23=5(Simplify both sides of the equation)

−7x−23+23=5+23(Add 23 to both sides)

−7x=28

−7x/−7=28/−7

(Divide both sides by -7)

x=−4

Step: Substitute−4 for x in y=5x+23:

y=5x+23

y=(5)(−4)+23

y=3(Simplify both sides of the equation)

x=−4 and y=3

y=mx+b

step-by-step explanation:

m slope

b y-intercept

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
