In cryptography, inverse functions are used by government agencies and other businesses to encode and decode information. The alphabet is A = 1, B = 2, C = 3, ... If the encoding function is y=4x+7 and the code numbers are 15, 67, 55, and 87, what is the encoded word? (Find the y values of the inverse.)

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
