The short answer is to solve one equation for one variable, then swap that variable in a different equation.
Example:
2x + 2y = 6
y-x = 1
Step 1: solve either equation for a variable: (#2) y = x+1
Step 2: substitute for your solved variable (I can substitute x+1 for y)
(#1) 2x + 2(x+1) = 6
2x + 2x + 2 = 6
4x + 2 = 6
4x = 4
x = 1
now use x=1 to solve for y in either original equation
<span>Tran is incorrect because he only has 1/3 of clay left. Noah as 2/4 or 1/2 left. 1/3 < 1/2 </span>
Answer:
I’m too lazy so just look at the picture.
Step-by-step explanation:
<span>It is undefined because it is one of the building blocks of geometry.
In order to define a term, we must have a definition of <u>all of the words</u> used to describe it. As this progresses, we would have a never-ending list of words to define; at some point, we must accept a few basic building blocks as being undefined.</span>
