Step-by-step explanation:
7p - 9 - p = 7p - p - 9 = <u>6</u><u>p</u><u> </u><u>-</u><u> </u><u>9</u>
.....
1st system: 2x = 14 <=> x = 7
2nd system: 2x = 4 <=> x = 2
Answer: x=-6
Step-by-step explanation:
Add 5 to both sides to get 2x by itself
Yes, subtract 1 from both sides to get 3x by itself so you can subtract 2x as to not get a negative x value
One common mistake would be to accidentaly adding or subtracting 1 or 5 when they are supposed to be added/subtracted. To avoid this just go back and check your awnser by plugging it in.
