Answer 1

Answer:

yes, t =-1 is solution if the equation

Step-by-step explanation:

See, here we have the equation:

2t+7+t = t+5

and we have value if t = -1

so replacing t by -1 in the equation :

2×(-1 ) +7+(-1) = -1 + 5

-3+7=4

4 = 4

since RHS=LHS SO IT IS VERIFIED

AND T= -1 is the solution

Answer 2

Answer:

ans =

Step-by-step explanation:

2(-1)+7+-1= -1+5

-2+7-1 = 4

-3+7 = 4

4 = 4

0 = 4-4

0 = 0
