The family trip to Grandma's consisted of both a train ride and a car ride. The average speed of the train ride was 74 miles per hour, and the average speed of the car ride was 50 miles per hour. The entire trip lasted 10 hours.
Let x be the number of hours the train ride lasted. Write an expression for the total distance of the trip, in miles.

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
