Answer: 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)
Answer:
x=−4 and y=3
