## duha2011 3 years ago oh sorry f=guys but i deleted my question by a mastake could u tell me the answer again the problem is 2y+7+-1 how do you solve this.???

1. Mertsj

2y+7+-1=2y+6

2. Mertsj

Add the like terms. And you are not solving it. You are simplifying.

3. KatrinaKaif

-4

4. karatechopper

wasnt it equal to -1? and not adding -1?

5. duha2011

oh yes

6. KatrinaKaif

2y + 7 = -1 (it was your original problem) 2y = -1 - 7 2y = -8 y = -4

7. duha2011

the problem is 2y+7=-1

8. karatechopper

so u want me to show u how kat got all tht?

9. KatrinaKaif

Understood?

10. KatrinaKaif

1) Your ultimate goal is to bring all the constants onto one side of the equal sign Therefore, lets move the + 7 to the other side by substracting 7 with -1, resulting -8

11. KatrinaKaif

Now your left with 2y = -8 Divide by 2 to get "y" by itself y = -8/2 y = -4 is your answer when simplified

12. karatechopper

nvm

13. duha2011
