Assign two variables for each problem, and write the equations. do not solve.

a basketball team stopped at a fast-food restaurant after a game. they divided into two groups. one group bought 5 chicken sandwiches and 7 hamburgers for a cost of $24.90. the second group sent $28.80 and bought 5 chicken sandwiches and 9 hamburgers. how much does a hamburger cost?

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
