Solve the equation below
tresset_1 [31]

Answer:

(-2, 3)

Step-by-step explanation:

<u>Substitute 2x + 7 for y in y = -2x - 1</u>

  • <u></u>2x + 7=-2x-1

Add 2x to both sides

  • 2x + 7 + 2x = -2x - 1 + 2x
  • 4x + 7 = -1

Subtract 7 from both sides.

  • 4x + 7 - 7 = -1 - 7
  • 4x = -8  

Divide both sides by 4.

  • \frac{4x}{4}= \frac{-8}{4}
  • x = -2

<u>Substitute -2 for x in y = 2x + 7</u>

  • <u></u>y = 2(-2)+7

Simplify both sides.

  • y = -4 + 7
  • y = 3

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