Answer:
x = -2
Step-by-step explanation:
6 - 2(x + 6) = 3x +4
6 -2x - 12 = 3x + 4
6 - 12 - 2x = 3x + 4
-6 -2x = 3x +4
-6 - 4 - 2x = 3x + 4 - 4
-10 -2x = 3x
-10 -2x + 2x = 3x + 2x
-10 = 5x
-10 / 5 = 5x/5
x = -2
I hope this helps!!
Answer:
x = -2
Step-by-step explanation:
6 - 2(x + 6) = 3x + 4
Step 1: Multiply -2(x+6)
6 - 2(x + 6) = 3x +4
6 - 2x - 12 = 3x + 4
Step 2: Distribute the left side ("6 - 2x - 12")
-2x - 6 = 3x + 4
Step 3: Add "-2x" to both sides.
-2x - 6 = 3x + 4
<u>+2x +2x </u>
-6 = 5x + 4
Step 4: Subtract "4" from both sides.
-6 = 5x + 4
<u>-4 -4 </u>
-10 = 5x
Step 5: Divide both sides by "5" to get x alone.
<u>-10</u> = <u>5x</u>
5 5
x = -2

Step-by-step explanation:
add the units mL's together
Divide 1080 by 1+3+5 which is 9
120 is 1
360 is 3
600 is 5
120:360:600
Its 0 because the slope would be one if it was a positive line and itd go up and across one unitl and it is undefined if it is parallel to the y axis
