Answer:

[tex]x=\frac{5-8y}{2}[/tex]

Step-by-step explanation:

1 Equation is given, so solving for "x" would mean an expression for "x", where

x = SOMETHING

First, we need to isolate x, so we need to take "8y" to the other side, we have:

[tex]2x+8y=5\\2x=5-8y[/tex]

Now, since we don't have "x" isolated yet, we need to take out the 2, so we will divide both sides by 2 to get x isolated. Shown below:

[tex]2x=5-8y\\x=\frac{5-8y}{2}[/tex]

So, x has this expression  [tex]x=\frac{5-8y}{2}[/tex]
