Do Now – Algebra 1 1) Take out HW!!!! 2) Use the Do Now sheet from yesterday. 3) Problem of the Day: Make sure to solve algebraically on the paper (not in your head!!!) 1) - 9 = x - 7 2) x + 6 = 10 3) - 6x + 7 = 7 4) x = 27 5) 3x + 8 = 11
Homework Answers: One-Step Equations #1) x= -.27#2) x= -21#3) x=9 #4) x=9#5) x=5#6) x= -4 #7) x=4#8) x=6#9) x= -15 #10) x= -2#11) x= -10#12) x=3 #13) x=25#14) x= -35#15) x=7 #16) x=7#17) x=12#18) x=4 #19) x=10#20) x=11
Homework Answers: Two-Step Equations #1) x=12#2) x= -9#3) x=9 #4) x= -7#5) x=1#6) x=3 #7) x= -9#8) x= -7#9) x=0 #10) x= -3#11) x=6#12) x=2 #13) x= -4#14) x=2#15) x=1 #16) x=11#17) x=10#18) x=0 #19) x= -7#20) x=7
Solve Equations with Like Terms Lets think of fruit… Think of each like term as different types of fruit Only compare apple with apple and oranges with oranges.
Solve Equations with Like Terms Same idea with like terms. Compare types of variables and exponents. With the given examples, tell me which ones are like terms 3, 11 2x, x 2x 4, x 4y, 5w 11k 3, 16m 3 -13, 9 -2, p
How do you solve equations with like terms?? First, combine any like terms that are on the same side. 2m + 5 – m = 14 m + 5 = 14 Now, solve as we did before… m + 5 = m = 9
Lets do some together… 1. 7x x = x x = 23
Try some on your own… 1) x + 7x = 7 2) 3 + 6x + 3x = 93 3) x + 2x = ) - 17 = - 2x+7x + 3 5) - x x = 21 6) 34 = - x - 7x - 6 7) 5x x = 13 8) -3x x = -54
