BEAT THE TESTI 1. Which of the following equations have the correct
solutions Select all that apply,
2x + 5 = 19; X = 7
3+x+2-x=16; x =3
x+2/5=2; x = 8
6 = 2x -8; x = 7
14 =1/3x+5; x = 18

Step-by-step explanation:

2x + 5 = 19; X = 7: Correct

2(7) + 5 = 19

14+5=19

3+x+2-x=16; x=3 : Incorrect

3+3+2-3=16

6+2-3=16

7-3=16

4=16

x+2/5=2; x = 8: incorrect

8+2/5=2

x= 8/5

6 = 2x -8; x = 7: correct

6 = 2(7) -8

6 = 14-8

14 =1/3x+5; x = 18: Incorrect

14 = 18/3+5

14 = 6+5

i think that you should ask google for the answer to that problem because if we don't know it google does

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
