Answer:

x=-4,   y=7

Step-by-step explanation:

-5x-10y=-50...(1)

Multiply both sides by -1:

5x+10y=50

5x=50-10y

x=(50-10y)/5

Substitute <u>x=(50-10y)/5</u> into second given eqaution:

10(50-10y)/5+8y=16

Cancel out common factor 5:

2(50-10y)+8y=16

100-20y+8y=16

-12y=16-100

-12y=-84

y=84/12

y=7

Substitute y=7 into equation (1)

-5x-10(7)=-50

-5x-70=-50

-5x=-50+70

-5x=20

x=-20/5

x=-4

Given that the two triangles are congruent for which value of x are the triangles congruent?
Whitepunk [10]

Answer: 1

Since the triangles are congruent, the side lengths will also be equal.

2x - 3 = x - 2

2x - x = - 2 + 3

x = 1

So if x is 1 then the two triangles will be congruent...
