Carolyn was asked to solve the following system of equations. Her work is shown. Problem: Carolyn's Work:
3x - 2y = 7
3x - 2(x+2) = 7
y = x + 2
y = x + 2
3x - 2x + 4 = 7
y = 3 + 2
x + 4 = 7
y=5
X = 3
(3,5)
what error did carolyn make? identify her mistake.

what is the solution to the system of linear equations?

step-by-step explanation:

i need more details sorry

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
