Question

Simplify the expression by adding (or subtracting) like terms: 5x + 5 + 2x + 5x − 5y − 2y − 2x

Answer 1

10x -2y +5 that might be the answer

Answer 2

`\huge \boxed{10x-7y+5}`

Explanation:

Step 1: Identify like terms.

`\displaysyle 5x+2x+5-2x-5y-2y+5`

Step 2: Rewrite using properties of operations when necessary.

`\displaystyle 5x+2x+5x-2x=10x`

Step 3: Simplify.

`\displaystyle 10x-5y-2y+5`

Step 4: Check by substitution.

`\displaystyle -5y-2y=-7`

Therefore, the correct answer is 10x-7y+5
