Answer:
Answer:
x=3 and y=1
Step-by-step explanation:
Let's solve your system by substitution.
x=3y;2x+4y=10
Step: Solvex=3yfor x:
x=3y
Step: Substitute3yforxin2x+4y=10:
2x+4y=10
23y+4y=10
10y=10(Simplify both sides of the equation)
10y
10
=
10
10
(Divide both sides by 10)
y=1
Step: Substitute1foryinx=3y:
x=3y
x=(3)(1)
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=1
