## isolape 3 years ago ax + r = 7 for r

1. mathslover

$\color{blue}{\text{Subtract ax both sides}}$

2. mathslover

$\large{\color{blue}{ax+r}=\color{red}{7}}$ $\large{\color{blue}{ax+r}-\color{red}{ax}=\color{red}{7-ax}}$

3. mathslover

Can you tell me what will you get @isolape ?

4. isolape

uhm. i wish i could honestly. but i have no idea how to do any of this.

5. mathslover

what is 3-3 ? @isolape

6. isolape

dosn't make any sense to me.

7. isolape

0

8. mathslover

so what will be : ax - ax ?

9. isolape

0...?

10. mathslover

yes, so we had : ax - r - ax .. can you simplify it now?

11. isolape

Wait so is that the new equation after we -ax on both sides? ax - r - ax

12. mathslover

yes

13. mathslover

ax-r-ax = 7 - ax

14. isolape

uhm, do you add ax on both sides now?

15. mathslover

ax-ax-r=7-ax

16. mathslover

Now, ax-ax = 0 ax-ax-r = 7-ax => 0 - r = 7-ax correct?

17. isolape

correct

18. mathslover

so we get r = ax - 7

19. mathslover

got it?

20. isolape

21. mathslover

yes

22. isolape

alright, i guess i got it. Thanks!
