Question

$2x + 3y + 10 - x - 2y - 4$.

1. circle each expression and box each equation.

5 \t$3x$ \t$5 + 7 = 20 - 8$ \t$y + 7$ \t$5 + 10 =$ \t$35 + 14 =$

1. identify the coefficients, constants, and variables in the expression $5x + 8y + 7 - 3x - y + 9$.

Explanation:

First Problem: Simplify $2x + 3y + 10 - x - 2y - 4$

Step1: Group like terms

$(2x - x) + (3y - 2y) + (10 - 4)$

Step2: Combine like terms

$x + y + 6$

Expressions are mathematical phrases without equality signs; equations have equality signs stating two expressions are equal.

Step1: Simplify the expression first

$(5x-3x)+(8y-y)+(7+9) = 2x + 7y + 16$

Step2: Define each component

• Variables: Symbols representing unknown values
• Coefficients: Numbers multiplied by variables
• Constants: Numbers without variables

Answer:

$x + y + 6$
