[DOC File]Simplifying and Combining Like Terms
https://info.5y1.org/2-step-addition-problems-pdf_1_e83e2a.html
When simplifying using addition and subtraction, you combine “like terms” by keeping the "like term" and adding or subtracting the numerical coefficients. Examples: 3x + 4x = 7x 13xy – 9xy = 4xy 12x3y2 - 5x3y2 = 7x3y2. Can you simplify? 4x3 + 4y3 11x2 – 7x 6x3y + 5xy3 Simplify the following: 1) 7x + 5 – 3x 2) 6w2 + 11w + 8w2 – 15w 3) 6x + 4 + 15 – 7x 4) (12x – 5) – (7x – 11 ...

Remember: addition/subtraction must be done before multiplication/division. Note: some inequalities have no solution and others are true for all real numbers. Example: Solving Inequalities (Multi-Step) Solve the following inequalities and graph the solution on the number line. 2y + 3 < 9 b. 3y + 2y > 15. Step 1: Opposite of add is subtract Step 1: Add like terms. So subtract 3 from both sides ...
