Select all of the equations below that are equivalent to: x + y = 13 Use properties of equality. Multi-select Choices: (A)3 + x + y = 15 (B)x + y + 2 = 15 (C)x + y + 4 = 19 (D)7 + x + y = 19

Identify equation and task: Identify the original equation and the task: x + y = 13, and we need to find equivalent equations. Compare with choice (A): Compare choice (A) 3 + x + y = 15 to the original equation. Add 3 to both sides of x + y = 13: x + y + 3 = 16. This does not match 15.

Identify equivalent equations

Full solution

Q. Select all of the equations below that are equivalent to:

\newline

x + y = 13

\newline

Use properties of equality.

\newline

Multi-select Choices:

\newline

(A)

3 + x + y = 15

\newline

(B)

x + y + 2 = 15

\newline

(C)

x + y + 4 = 19

\newline

(D)

7 + x + y = 19

Identify equation and task: Identify the original equation and the task: $x + y = 13$ , and we need to find equivalent equations.
Compare with choice (A): Compare choice (A) $3 + x + y = 15$ to the original equation. Add $3$ to both sides of $x + y = 13$ : $x + y + 3 = 16$ . This does not match $15$ .
