A variable is a symbol, usually a letter, that represents an unknown number.
a, b, n, x, y
3x + 4 = 19
x = 5
Name the opposite of the integer.
-17
17
6 + (-8)
-2
-9 + c = 21
c = 30
-3r = -15
r = 5
Simplify by combining like terms.
-3a + 9c + 8c
-3a + 17c
9b - 2 = 34
b = 4
Name the opposite of the integer.
0
0
5 - 19
-14
-1 = c - 1
c = 0
x ÷ 4 = -3
x = -12
How would you graph the point (4, -1)?
Starting from the origin, move to the right 4 spaces and move down 1 space.
-5a + 2 = 32
a = -6
Compare the integers using > or <.
-3 _____ 2
-3 < 2
-6 x 3
-18
-5 + y = -15
y = -10
b ÷ 9 = 4
b = 36
Absolute value is the distance a number is from zero. What is the absolute value of -3?
|-3| = 3
4 - 3v = 40
v = -12
Compare the integers using > or <.
