QuestionWhat property of equality solves $-15+x=18$ ? (A) Addition (B) Subtraction (C) Multiplication (D) Division

Studdy Solution

STEP 1

Assumptions1. The equation is $-15+x=18$ . The properties of equality are defined as follows (A) Addition Property of Equality If $a=b$ , then $a+c=b+c$ (B) Subtraction Property of Equality If $a=b$ , then $a-c=b-c$ (C) Multiplication Property of Equality If $a=b$ , then $ac=bc$ () Division Property of Equality If $a=b$ and $c≠0$ , then $a/c=b/c$

STEP 2

In order to solve the equation $-15+x=18$ , we need to isolate $x$ on one side of the equation. To do this, we need to eliminate $-15$ from the left side of the equation.

STEP 3

We can eliminate $-15$ by adding $15$ to both sides of the equation. This is because adding $15$ to $-15$ gives $0$ , and the equation becomes $x=18+15$ .

STEP 4

This step of adding $15$ to both sides of the equation corresponds to the Addition Property of Equality, which states that if $a=b$ , then $a+c=b+c$ .
Therefore, the property of equality used to solve the equation $-15+x=18$ is the Addition Property of Equality.
