Y=6x 2x+3y=20 solving equation using substitution
2 answers:
Answer:
x = 1, y = 6
Step-by-step explanation:
y = 6x
2x + 3y = 20
Plug y as 6x in the second equation and solve for x.
2x + 3(6x) = 20
2x + 18x = 20
20x = 20
x = 1
Plug x as 1 in the first equation and solve for y.
y = 6(1)
y = 6
Answer:
y=6 , x=1
Step-by-step explanation:
y=6x
2x+3y=20
Substitute 6x into y because y=6x.
2x+3(6x)=20
2x+18x=20
20x=20
<u>x=1</u>
Then subsitiute 1 into the first equation in x value
y=6(1)
<u>y=6</u>
