## sonja_lee2 3 years ago solve the equation for y. 4x+7y-5x=8x-4+4y

1. Chlorophyll

Arrange all y terms to the left side, the rest to the right side: Can you show it?

2. sonja_lee2

how would i do that?

3. Chlorophyll

Since 4y currently on the right side, move it to the left first

4. sonja_lee2

so would i minus 4y to the 7y?

5. sonja_lee2

then is comes out to 4x+3y-5x=8x-4 right?

6. sonja_lee2

-1x?

7. Chlorophyll

then move -x to the right side

8. sonja_lee2

so i would add -x to 8x?

9. Chlorophyll

when you switch the SIDE, then the SIGN changed! 8x + x = ...

10. sonja_lee2

9x

11. sonja_lee2

3y=9x-4?

12. Chlorophyll

Final step is divide both side by 3 => y = ...

13. Chlorophyll

@sonja_lee2 Where are you?

14. sonja_lee2

y=9x-4/3?

15. sonja_lee2

y=3x-1.333

16. Chlorophyll

Actually, keep the fraction y = 3x - 4/3

17. sonja_lee2

oh okay

18. sonja_lee2

can u also help me with solving for w. -3u-w=u+5w

19. Chlorophyll

Just open the new post for each new question, so more helpers can solve, too :)
