One Step Equations
Solve for x:
-4 + x = 6
X = 10
Solve for x:
3x + 2 = 14
X = 4
Solve for x:
2(x - 3) = 8
X = 7
Solve for c:
4c + 2c = 6 + 36
C = 7
Why do we add 4 on both sides of this equation?
-4 + x = 3
Because - 4 + 4 = 0 and that is how we isolate the x.
Solve for a:
a - 12 = 14
a = 28
Solve for y:
-5 - y = 20
Y = -25
Solve for y:
y(5 + 2) = 21
Y = 3
Solve for m:
-5 + 2m - 4 = 11
M = 10
Why do we divide on both sides by 6?
12 = 6x
Because 6/6 =1 and that is how we isolate the x.
By making it into a 1x.
Solve for p:
6p = 36
P = 6
Solve for t:
(t + 6) / 8 = 3
t = 18
Solve for a:
-9 = - (7 + x)
X = 2
Solve for y:
10y + 3 - 2y - 3y = 48
Y = 9
Why do we multiply by 5 on both sides?
y/5 = 4
Because 5 * (y/5) = 5y/5 = 1y
Solve for c:
(c / 9)= 5
C = 45
Solve for a:
(7a) / 2 = 14
a = 4
Solve for p:
20 = -x (6 + 4)
X = -2
Solve for x:
-30 - 5 - x = 6x
X = -5
Solve for x:
8 = (1/3) * x
X = 24
:O
Solve for x:
8x = 5x - 36
X = -12
-_- :O
Solve for x:
5 (2x - 7x) = 75
X = -3
:O O:
Solve for w:
(-3 + 12x + 3x - 9) / 4 = 12
X = 4
:O
What are two ways we can start solving this equation?(x/2) - 3 = 7
First way: + 3 on both sides.
Second way: multiply by 2 on both sides. Can someone show us how we do that?
