adding one step equations
a + 7 = 10
a = 3
4=a - 5
a = 9
a/8 =7
a = 56
5a = 25
a = 5
a/7 = 9
a = 63
-20 = x + 9
x = -29
a - 21 = 49
a = 70
x + 80 = 15
a =-65
4a = 60
a = 15
a/8 = 12
a = 96
a + 21 = 60
a = 39
50= a - 25
a = 75
What is the goal of solving equations?
know the value of the unknown
6a = 54
a = 9
a/-10 = 15
a = -150
a + 5 = -40
a = -45
a - 10 = -50
a = -40
x - 25 = -15
x = 10
-10a = -220
a = 22
a/-8 = -12
a = -96
- 26 + a = 24
a = 50
x - 25 = -30
x = -5
True OR False
Is x=5 a solution for the equation -2 x = 10?
False
-11x = 275
x = -25
a/-15 =9
a = -135
