Question

1.(4x/9)+(x-10/9)
2.(t^2+6t/t-1)-(7/t-1)

Show work

Answer 1

I'll rewrite this because I can't see why the ( ) are where they are right now
1. 4x/9 +(x-10)/9 and
2. (t^2+6t)/(t-1) - 7/(t-1)
is this correct?

Answer 2

it supposed to be in fraction format

Answer 3

with the order of operations, you need to write it the way I did, else, for example, the second term in 1 would x (undivided by 9) - 10/9. Anyways, so, since you have the same denominator for both, you can all put it in the same fraction :
1. (4x+x-10)/9 = (5x-10)/9
2. (t^2+6t-7)/(t-1)
makes sense?

Answer 4

its addition and substraction of rational expressions
