X=3y<br>2x+4y=10<br>solve using substitution​
Blababa [14]

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)
