Like terms
What are like terms?
Numbers, values, terms that share the SAME variable (or no variable at all)
Solve for x
x-4=10
x=14
find the absolute value of
l -3 l
3
Solve for x
2x + 4 = 3x
2x + 4 = 3x
4 = x
T or F
There is only one variable in the equation
False. There are always two or more variables
Give two examples of like terms. One with a variable, one without
3x, 2x
4, 6
6a, 5a
72, 13
Solve for t
t+2t=9
t+2t=9
3t=9
t=3
find the absolute value of
l -8 l + l 5 l =
13
Solve for g
4g -2 = 6g -2
4g -2 = 6g -2
4g = 6g
0 = 2g
0 = g
Solve for y
2x + y =12
y=12-2x
3x+4-x+14
Combine the like terms
2x+18
Solve for x
3x-7=23
3x-7=23
3x=30
x=10
Find the absolute value of
- l 3 * -5 l =
-18
4x + 2 = 6x
4x + 2 = 6x
2 = 2x
x = 1
Solve for y
8 - 4x = 2y
4 - 2x = y
3h + 4h -12 = 2
combine like terms and rewrite the equation
7h - 12 = 2
-5 + 2x = 3
-5 + 2x = 3
2x = 8
x = 4
solve this equation if possible
l 3x + 3 l = -6
no (no solution)
Solve for y
2y + 3 = -5y -11
2y + 3 = -5y -11
7y + 3 = -11
7y = -14
y = -2
Solve for y
3x + x = 2y - 8
4x = 2y - 8
4x + 8 = 2y
2x + 4 = y
Distribute, then combine like terms
2(m+6)-3+m
2m+12-3+m
2m+m+12-3
3m+9
solve for b
2(2b-4) = 16
2(2b-4) = 16
4b-8=16
4b=24
b=6
solve this equation if possible
l 2x - 14 l = 6
2x-14 = 6 2x-14=-6
2x=20 2x=8
x=10 x=4
3(2y + 5) = 2 (2y + 10)
3(2y + 2) = 2 (2y + 10)
6y+6=4y+20
2y+6=20
2y=14
y=7
Solve for y
2y + 3x = y +4x
2y + 3x = y + 4x
y + 3x = 4x
y = x
