If 1/2 subtracted from a number and the difference is multiplied by 4, the result is 5. what is the number.

The setup is a follows:

4(x - 1/2) = 5

4x - 2 = 5

4x = 7

x = 7/4 = 1 3/4

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

if x = 1, then the answer is 3.5
