Answer:
1. x = -2
2. x=-5
Step-by-step explanation:
1) 7x + 14 = 0
Subtract 14 from each side
7x+14-14 = 0-14
7x = -14
Divide by 7
7x/7 = -14/7
x = -2
2) -2x - 10 = 0
Add 10 to each side
-2x-10+10=0+10
-2x = 10
Divide by -2
-2x/-2 = 10/-2
x=-5
Answer:
1. -2
2. -5
Step-by-step explanation:
7x + 14 =0
You move 14 to the other side and make it a minus, 0 - 14, is -14, divided by 7 on both sides that will get you to -2.
-2x - 10 = 0
You move the -10 on the other side and make it a plus sign, 0 + 10, is 10, keep in mind that a negative and a negative make a positive. Then you divide both the sides with 2.
