The following were the scores of 25 pupils in the class: 62,80,52,71,38,44,51,50,41,38,42,45 ,54,34,28,55,60,59,40,40,50,40,28,3 2,40 Use the data to analyze and report pupils’ performances
What is the mean of the numbers above?

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
