X + Y = 10
X + 2Y = 16
First, subtract Y from both sides in X + Y = 10.
X = 10 - Y
X + 2Y = 16
Next, plug X into X + 2Y = 16.
X = 10 - Y
10 - Y + 2Y = 16
Afterwards, simplify.
X = 10 - Y
Y + 10 = 16
Subtract 10 from both sides in Y + 10 = 16
X = 10 - Y
Y = 6
Finally, plug Y into X = 10 - Y
X = 10 - 6
Y = 6
Simplify
X = 4
Y = 6

<h3>What is a ray?</h3>
A ray is a line segment with arrow head. The arrow head helps in pointing to the direction of the ray. The arrow head may appear at the both ends of a ray signify that the ray continues in both direction.
Often times in the field of science, rays are used to signify direction, while the length of the line segment signify magnitude.
Bearing in mind that ray can be in one direction or two directions, we now look at the picture to point out the rays to be:

Do you need it in Exact form or Decimal?
Answer: 9(3 + 2r)
<u>Step-by-step explanation:</u>
27 18r
∧ ∧
<u>3</u> 9 <u>2</u> 9r
∧ ∧
<u>3</u> <u>3</u> <u>3</u> <u>3r</u>
27: 3 * 3 * 3
18r: 2 * 3 * 3 * r
Common Factors are 3 * 3 = 9
27: 9 * <u>3</u>
18: 9 * <u>2r</u>
27 + 18r = 9(3 + 2r)
