Suppose the sales tax rate in your area is 4.5%. Complete the explanation of how to determine the total
cost, including tax, of an eReader that costs $145. Round to the nearest cent if necessary.
(select) $145 by the tax rate expressed as a decimal (0.045) and add the result to $145. Or, (select)
$145 by the sum of select) The total cost is $

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
