Question

Add or subtract the linear expressions and simplify: Show your work! (3x + 7) + (8x + 2)

Answer 1

$(3x+7)+(8x+2)$

First you remove the parenthesis:

$=3x+7+8x+2$

Add or substract similar terms (you can just add or substract terms with the same variable, in this case you can just add the terms with x between them and the terms without x between them)

You can ordered the equation to get the similar terms next to each other:

$=3x+8x+7+2$

And then add or substract:

$=11x+9$Then, the addition of the given linear expressions is equal to 11x+9
