Solve each system of linear equations using substitution.
1. y= 2x - 1 and y=x-8
2. y = 5x + 4 and y= -5x - 6
3.
y = -x - 1 and y = -2x - 6
4. y=-4x + 2 and y=-2x​

Respuesta :

Answer:

1. x = -7

2. no solution

3. -5

4. x=1

Step-by-step explanation:

1. x-8= 2x-1

-8 = x - 1

-7  = x

2. 5x +4 = -5x - 6

+5x           +5x

4=-6 N/A

3. -x - 1 = -2x -6

+2x

x-1= -6

x= -5

4. -2x = -4x + 2

2x = 2

x=1
