Y=2x+5
2(2x+5)+4x=10
4x+10+4x=10
8x=20
So there's one solution, x=2.5
Answer:
x=-8 y=6
Step-by-step explanation:
Add the two equations together. This cancels the x and gets us y=6
Then substitute y in more the first equation which gets us -8
the answer is x= 10.
the steps would go like this.
4 + 3/5 × (15 + 2x) = 25
4 + 9 + 6/5x = 25
13 + 6/5x = 25
65 + 6x = 125
6x = 125 -65
6x = 60
x = 10

Answer:
A rectangle is a two - dimensional shape, so let me explain using it as an example.
The diagonal of a rectangle divides the rectangle into two triangles that are congruent (the same size and shape.)
Another example is parallelogram; the diagonal of a parallelogram also divides the figure into two separate shapes that are congruent.
Hope this helps!
