Answer:

(-2, 3)

Step-by-step explanation:

Substitute 2x + 7 for y in y = -2x - 1

  • [tex]2x + 7=-2x-1[/tex]

Add 2x to both sides

  • [tex]2x + 7 + 2x = -2x - 1 + 2x[/tex]
  • [tex]4x + 7 = -1[/tex]

Subtract 7 from both sides.

  • [tex]4x + 7 - 7 = -1 - 7[/tex]
  • [tex]4x = -8[/tex]  

Divide both sides by 4.

  • [tex]\frac{4x}{4}= \frac{-8}{4}[/tex]
  • [tex]x = -2[/tex]

Substitute -2 for x in y = 2x + 7

  • [tex]y = 2(-2)+7[/tex]

Simplify both sides.

  • [tex]y = -4 + 7[/tex]
  • [tex]y = 3[/tex]

Therefore, the answer is (-2, 3).
