Step-by-step explanation:
I don't know I just Lucky guessed but hope it helps and I was right
Simplifying
4+-7=8t+3
Reorder the Terms
-7+4=8t+3
Reorder The terms again
-7+4t=3+8t
Solving for the variable T
Move all terms containing t to the left, and all other terms to the right
Add -8t to each side of the equation
-7+4t+-8t=3+8t+-8t
Combine like terms
4t+-8t=-4t
7+-4t=3+8t+-8t
Combine like terms
8t+-8t=0
-7+-4t=3+0
-7+-4t=3
Add 7 to each side of the equation
-7+7+-4t=3+7
Combine like terms
0+-4t=3+7
-4t=3+7
Combine like terms 3+7=10
-4t+10
Divide each side by 4
t= -2.5
Simplifying
t= -25
