If the temperature when you woke up was -10°f, and the temperature at mid-day was 42°f, what is the difference in temperature? if at bedtime, the temperature was a decrease of the high mid-day temperature by 1/4 the difference in temperature ( from morning to mid-day), what is the temperature when you go to bed?

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
