Hello : 
<span>2x + 3 < 19 and 2x − 3 ≤ -7 :
the system :
</span><span>2x + 3 < 19 .....(1)
2x − 3 ≤ -7......(2)
by (1) : 2x </span>< 16
             x < 8
by(2) : 2x  ≤ -4

The graph shows two lines, A and B.
Harlamova29_29 [7]

Answer with explanation:

<u>Part A: </u>

One solution.

The number of points of intersection represents the number of solutions. Since the two lines only intersect at one point, there is only one solution.

<u>Part B:</u>

(3, 4)

The point(s) of intersection marks the solution(s) to the lines. Since lines A and B intersect at the point (3, 4), the solution to the equation of their lines is (3, 4), or x=3, y=4, as coordinates are written as (x, y).
