2(1 – 8x) = 1/2 (8 - 64x)​
faust18 [17]

Answer:

x=\frac{1}{8}

Step-by-step explanation:

A quick review on PEMDAS, the order of how to solve an equation:

P - parentheses. When parentheses are being used, you have to do everything inside them before doing everything outside of them.

E - exponents. We'll skip these, since there aren't any exponents we need to worry about in this equation.

M/D - multiplication/division. I include these both together because they can be done at the same time.

A/S = addition/subtraction. Can also be done at the same time.

Some other things to note:

You add all the things with an x attached to it, and you add all the things without an x attached to it, and these never cross.

When you bring something from one side of an equal sign to another, you make it negative.

Let's solve for x using what we've learned:

2(1-8x)=\frac{1}{2} (8-64x)\\2-16x=4-32x\\16x=2\\x=\frac{2}{16} \\x=\frac{1}{8}
