Scribe Post for Jan. 30 2009

Today at Math, we did number of the day. Today's number is 2969.402
After that Mr. Isfeld checked our homework from yesterday.

1. 6 - 3x = -6

To remove 6 and leave 3x, subtract 6 from both sides of the operation
6 - 6 - 3x = -6 - 6
-3x = -12
To remove -3 and just leave x, divide both sides by -3
-3x/-3 = -12/-3
x = 4

To verify:
6 - 3x = -6
6 - 3(4) = -6
6 - 12 = -6
-6 = -6

2. 5x/4 + 3 = -7

To remove 3, subtract 3 from both sides of the operation
5x/4 + 3 - 3 = -7 - 3
5x/4 = -10
To remove 4, multiply both sides by 4
5x/4 (4) = -10 (4)
5x = -40
5x/5 = -40/5
x = -8

To verify:
5x/4 + 3 = -7
5 (-8)/4 + 3 = -7
-40/4 + 3 = -7
-10 + 3 = -7
-7 = -7

3. x/5 = -3/4

To remove 5, multiply both sides by 5
x/5 (5) = -3/4 (5)
x = -3.75

To verify:
x/5 = -3/4
-3.75/5 = -0.75
-0.75 = -0.75

I choose Daylan for the next scribepost
