Cillian and Dorian are 15 miles apart on a bike path when they start biking toward each other. Cillian rides at a constant speed of 3 miles per hour, and Dorian rides at a constant speed of 2 miles per hour. How long does it take until they meet? Use a table, double number line, tape diagram or another strategy to show your thinking. (Please answer quickly this is due in 15 minutes and im being timed)​

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
