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.

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
