X + y = 5 2x - y = -3 a. One Solution Infinitely
b. Many Solutions
c. No Solutions
I do not understand this can someone please help solve and explain?

c. No solutions

Step-by-step explanation:

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2
