Question

Name the property or definition illustrated below

If y = 3x and 2x + 4y = 12, then 2x + 4(3x) = 12

Answer 1

Answer: Substitution

Explanation:

GIVEN:

y=3x

2x+4y=12

Then, 2x+4(3x)=12

-----------------------------------------

Substitution: replacing one variable in terms of another variable.

As we can see from the given aspects, y=3x, and the conclusion expression has no y instead of 3x. This means it represented y in terms of x, which fits the definition of substitution that replaces one variable.

Hope this helps!! :)
