Combine like terms.

$9y + 3+ y - 2 + 5\\10y + 3 - 2 + 5\\10y + 1 + 5\\10y + 6$

$10y + 6$

Follow the steps in part (a).
Remember that you can only combine terms that are identical
($4x^{2}$ cannot be combined with $3x$ or $2x$).

Start by distributing throughout the parentheses.

$2\left(3x - 2\right) + x - 1 \\6x - 4 + x - 1$

Then continue simplifying by combining like terms and using the Order of Operations.

$6x - 4 + x - 1\\ 7x - 4 - 1 \\7x - 5$

$7x - 5$

Follow the steps in part (c).
Don't forget to distribute throughout the parentheses before combining like terms!
