Answer: (7, 20)

Concept:

There are three general ways to solve systems of equations:

  1. Elimination
  2. Substitution
  3. Graphing

Since the question has specific requirements, we are going to use <u>substitution </u>to solve the equations.

Solve:

<u>Given equations</u>

y = 3x - 1

2x + 6 = y

<u>Substitute the y value since both equations has isolated [y]</u>

2x + 6 = 3x - 1

<u>Add 1 on both sides</u>

2x + 6 + 1 = 3x - 1 + 1

2x + 7 = 3x

<u>Subtract 2x on both sides</u>

2x + 7 - 2x = 3x - 2x

\boxed{x=7}

<u>Find the value of y</u>

y = 3x - 1

y = 3(7) - 1

y = 21 - 1

\boxed{y=20}

Hope this helps!! :)

The equation A = x(x - 7) describes the area, A, of a rectangular flower garden, where x is the width in feet.

x(x-7)=8

x^2-7x-8=0

(x-8)(x+1)=0

so x=8 (and -1 but width can’t be negative)

So your answer is C. 8
