ORIGINAL PROBLEM
“S”
Example #1
2x + 3x + 5 = 15 + 20 – 5
5x + 5 = 30
Example #2
-x = 12
Example #3
-x + 5x – 5 + 2 = 7 – 2
4x – 3 = 5
“M”
Example #1:
5x + 5 = 30
-5 -5
5x = 25
Example #2:
-x = 12
Example #3:
4x – 3 = 5
+3 +3
4x = 8
“I”
Example #1:
5x = 25
5
5
x=5
Example #2:
-1x = 12
-1
-1
x = -12
Example #3:
4x = 8
4 4
x=2
“C”
Example #1:
2x + 3x + 5 = 15 + 20 - 5
2(5) + 3(5) + 5 = 15 + 20 – 5
10 + 15 + 5 = 30
25 + 5 = 30
30 = 30
Example #2:
-x = 12
-(-12) = 12
12 = 12
“C”
Example #3:
-x + 5x – 5 + 2 = 7 – 2
-2 + 5(2) – 5 + 2 = 5
-2 + 10 – 5 + 2 = 5
8–5+2=5
3+2=5
5=5
