Answer:

The value of the equation for x is x=\frac{64}{3}.

Step-by-step explanation:

Consider the provided equation.

\frac{1}{2}+\frac{1}{4}=16

We need to solve the equation for x.

Add the like terms as shown:

\frac{2x+x}{4}=16

\frac{3x}{4}=16

Multiply both the sides by 4/3.

\frac{3x}{4}\times \frac{4}{3}=16\times \frac{4}{3}

x=\frac{64}{3}

Hence, the value of the equation for x is x=\frac{64}{3}.

Given the following formula, solve for a.
Elena L [17]

Answer:

A. a = 2s - b -c

Step-by-step explanation:

Rearrange the equation in a way that you have only a on one side. When solving equations you can add, subtract, multiply or divide by the same number/variable/expression on the both sides.

s = \frac{a + b + c}{2}

Multiply by 2 to get rid of the fraction.

s \cdot 2 = \frac{a + b + c}{2} \cdot 2

On the right side the 2 cancels out:

s \cdot 2 = a + b + c

On the right side next to a are still b and c. But we want a alone. Subtract b.

s \cdot 2 - b = a + b + c - b

b - b on right side gives 0.

s \cdot 2 - b = a + c + 0

The step above is usually skipped, because number + 0 = number.

s \cdot 2 - b = a + c

Next to a there is still c. Subtract c.

s \cdot 2 - b - c = a + c - c

c - c on the left is 0.

s \cdot 2 - b - c = a

So our answer is:

s \cdot 2 - b - c = a

It can be rewritten to (change sides):

a = s \cdot 2 - b - c

And s · 2 can be rewritten to 2s:

a =  2s - b - c
