Answer: x = 13
Step-by-step explanation: When solving an equation like this, we are trying to get our variable which is our letter by itself.
So we first want to ask ourselves what is the 14 doing to <em>x</em>. Well, we can see that it's being added to <em>x</em> so to get <em>x</em> by itself, we will do the opposite of addition which is subtraction. So we subtract 14 from both sides of the equation.
The +14 -14 cancels out so we're left with <em>x</em> on the left.
On the right, we must subtract 14 from 27 to get 13.
So we have x = 13 which is the solution to this equation.

Answer:
all real numbers.
Step-by-step explanation:
9x - 8y = 1
18x - 16y = 2
if you look at the first equation, you can figure out what y equals.
9x - 8y = 1
<em>add 8y to both sides</em>
9x = 1 + 8y
<em>subtract 1 from both sides</em>
9x - 1 = 8y
<em>divide both sides by 8</em>
= y
<em />
now, substitute y in the second equation.
18x - 16y = 2
18x - 16(
) = 2
18x - 2(9x - 1) = 2
18x - 18x +2 = 2
2 = 2
the answer is <em>all real numbers, </em>because regardless of what x equals, 2 will always equal 2.
