Question

2x + 8y=5 solve for x

Answer 1

Answer:

$x=\frac{5-8y}{2}$

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:

$2x+8y=5\\2x=5-8y$

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:

$2x=5-8y\\x=\frac{5-8y}{2}$

So, x has this expression  $x=\frac{5-8y}{2}$
