## anonymous one year ago Which value of y makes the equation true? y – 6.3 = –2.2 y =

1. Nnesha

how would you cancel out -6.3 from left side ? would you add ,subtract or divide ??

2. anonymous

subtrade but i tihnk its -2.2

3. Nnesha

well it's already negative on left side - times - = add not subtract

4. Nnesha

so to cancel out -6.3 you should add 6.3 both sides do it let me know what you get

5. Michele_Laino

hint: if I add 6.3 to bth sides, I get this: $\Large y - 6.3 + 6.3 = - 2.2 + 6.3$ please simplify

6. Michele_Laino

oops...to both sides...

8. Nnesha

4.1 0

11. Nnesha

yes right so left side 6.3 and -6.3 cancel each other out and right side is 4.1 that's it

12. Nnesha

now you can check your answer replace y with 4.1$\huge\rm 4.1-6.3=-2.2$ solve left side if both sides equal then -2.2 is100% right
