<span>We want to check how many intersections line A and B have, that is, we want to check how many common solutions do these equations have:
</span>
i) 2x + 2y = 8
ii) x + y = 4
<span>
use equation ii) to write y in terms of x as : y=4-x,
substitute y =4-x in equation i):
</span>2x + 2y = 8
2x + 2(4-x) = 8
<span>2x+8-2x=8
8=8
this is always true, which means the equations have infinitely many common solutions.
Answer: </span><span>There are infinitely many solutions.</span><span>

Answer:
P = 4x - 2
Step-by-step explanation:
Perimeter is all the side lengths added together.
Step 1: Set up expression
P = 2x - 5 + 5 - x + 3x - 2
Step 2: Combine like terms
P = 4x - 2

To calculate the perimeter of a triangle, add the length of its sides. For example, if the sides of a triangle are a, b, and c, the perimeter of the triangle is P = a + b + c.
Since all three sides of the triangle are the same length, you can multiply the length of each side by 3 to get the perimeter.
To find the circumference of a circle, multiply the diameter of the circle by π (pi). The circumference can also be calculated by multiplying 2 x radius by pi (π = 3.14).
