20 points! .. which expression is equivalent to the given expression? −(1/2y + 1/4)

a. −1/4 (1+2y)
b. 1/4 (2y−1)
c.−2 (1/4y−1/8)
d. 2 (1/8−1/4y)

Step-by-step explanation:

- (1/2y + 1/4)distribute thru the parenthesis

-1/2y - 1/4

A. -1/4(1 + 2y)...distribute thru the parenthesis

    -1/4 - 2/4yreduce and rearrange

    -1/2y - 1/4

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
