Answer:

x = 4

y = 30

Step-by-step explanation:

  • Since y = 8x - 2, substitute into 2nd equation
  • This gives you 3x + 8x - 2 = 42
  • Add 2 to both sides
  • 11x = 44
  • Divide both sides by 11
  • x = 4
  • Put this value into either equation
  • I choose the first one
  • y = 8x - 2 = 8 × 4 - 2 = 32 - 2 = 30

Answer:

x=4

y=30

Step-by-step explanation:

First re-write the system like this:

[tex] - 8x + y = - 2 \\ 3x + y = 42[/tex]

Now substitute them together:

[tex] - 11x = - 44[/tex]

So

[tex]x = 4[/tex]

put x=4 in one of the equations

[tex]3(4) + y = 42 \\ \\ y = 30[/tex]

so

x=4

y=30
