One-Step Equations
-8 + x = 4
x= 12
6x – 13 = 11
x= 4
4x - x + 3 = 6
x = 1
x - 2 = 6
x = 8
-3 + 4a -5 -2a + 6 + (-a)
a-2 or 1a-2
What will the answer be if you multiply two numbers with the same sign?
Positive
x + 12 = 0
x= -12
3x + 5 = 14
x= 3
3(2x - 2) = 30
x = 6
-5p + 1 = 6
p = -1
What is the variable in this equation?
9x - 10 = 8
x
What will your answer be when you divide two numbers with opposite signs?
negative
x + 2 = -16
x= -18
3x + 13 = -8
x= -7
x + 4x - 7 = 23
x = 6
2n+10 = 4
n = 2
Simplify
3a + 2 -(-2a) + 5
5a + 7
When adding -10 and -8, what will the answer be?
-18
5x = -80
x= -16
x/2 + 5 =10
x= 10
3(x + 6) + 2 = 26
x = 2
5(m-3) = 4
m = 19/5
When adding or subtracting opposite signs, you will do what to the two numbers?
subtract and keep the sign of the larger number
What do you get if you add 5 and -10?
-5
-2x = 10
x = -5
x/3 - 6 = -3
x= 9
2(5x + 8) = -14
x = -3
3(𝑥 − 9) = −3
x = 8
Solve...
-10 - (-13) =
3
Solve:
-5 - (-2) =
-3
