Identify the number of solutions:
5x + 4 = 5x + 4

0,4) : not a solution

(-2,4) ; solution

(0,5) : solution

(-2,7) : solution

(-4,1) : not a solution

(-1,1) : not a solution

(-1.5,3.5) : solution

any point that falls in the grey area is a solutionif ur points lie on a dashed line, it is not a solution...but if ur points lie on a solid line, it is a solution

Step-by-step explanation:

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
