If the problem is (x+7) - (-x-t) does it = x+7+x+t ??

For all real numbers x and t:
(x + 7) - (-x - t) = x + 7 + x + t = 2x + t + 7

x+7 times x+t

No, it is x+7+x-t

it = 7+0-t= 7-t
this is the anser bcuz the x's cancel out out to make 0, 7 just stays by its self bcuz there r no other common factors the t had to b subtracted

(x+7)-(-X-T)=X+7-(-x)-(-T)=x+7+x+T

yes that is correct! (x+7)-(-x-t) does equal x+7+z+t

(x+7) - (-x-t)
=(X+7)-(-X)-(-t)
====> -(-X) =+X
====> -(-t) =+t
=(X+7)+X+t
=X+7+X+t
Yes it si correct
and it is can be simplified again
=X+7+X+t
=2X+t+7

yes, simplified would be 2x+t+7

u distribute the minus sign into (-x-t) to make it x+t
