What is the first step in solving equations?
D - Distribute
Solve:
2(x - 7) = 10
x = 12
Solve:
6 + 10x - 4x = x +1
x = -1
Solve:
-2(v - 2) = -3 - 2v
No Solution
What is a proportion?
Two ratios set equal to one another.
What is the second step in solving equations?
C - Combine like terms
Solve:
5(x + 2) = -20
x = -2
Solve:
-7x - 10 = -8x - 4x
x = 2
Solve:
-4(v + 3) = -12 - 4v
Infinite Solution/All Real Numbers
Solve:
10/3 = x/6
x = 20
What is the third step in solving equations?
M - Move variables to one side
Solve:
3(2 + x) = 5x + 16
x = -5
Solve:
10 - 8x = -2x + 4x
x = 1
Solve:
-3(v + 4) = 2v - 37
v = 5 , 1 solution
Solve:
(x-7)/8 = 5/4
17
What is the fourth step in solving equations?
A - Undo addition or subtraction
Solve:
-152 = 4x - 4(6x + 13)
x = 5
Solve:
13 + 4x + 3x = 3x + 1
x = -3
Solve:
4(k - 8) = -32 + 4k
Infinite Solutions/All Real Numbers
Solve:
p/4 = (p-1)/6
-2
What is the final step in solving equations?
M - Undo multiplication or division
Solve: 5x + 2(1 - x) = 2(2x - 1)
x = 4
Solve:
-5 + 7 + 2x - 3x = x - 8
x = 5
Solve:
-(3 - 6b) = 6b + 5
No Solution
Solve:
10/(n+3) = 8/(n-4)
