Question

Directions: Solve each system of equations by substitution. Check your solutions.

1. y=2x
x+y=6

2. 5x+10y=3
x=-1/2y

3. y-x=3x+2
2x+2y=14-y

ty in advance, I need it for 10 minutes if 10 mins pass, it's okay I'll wait.​

Answer 1

1. x=2 y=4

or (2,4)

2. x= -1/5, y= 2/5

or (-1/5, 2/5)

3. x= 4/7, y= 30/7

or (4/7, 30/7)

Hope this helped!
