One-Step Equations
x+5=12
x = 7
2u + 2 = 4
u = 1
4(x+1)=24
x = 4
What is our end goal for solving equations?
Isolate the variable
w/-12 = -6
w = 72
-3t - 6 = -12
t = 2
6(x−3)=12
x = 5
How old is Mr. Williams?
25
-56 = 7x
x = -8
-5x - 10 = 40
x = -10
-2(2a - 8) = 32
a = -4
How do we isolate the variable?
Opposite operation
r - 4 = -121
r = -117
2.9 = -1.9 + 0.6x
x = 8
78 = -3(-4y + 6)
y = 8
What state was Mr. Williams originally from?
Ohio
x / 2.4 = 36
x = 86.4
4x - (3/8) = 5/8
x = 1/4
(1/3) (9p - 12) = 26
p = 10
