2t+7=-1
The object is to get t alone on one side.
Subtract seven from both sides.
Then, divide both sides by two.
To solve the equation 2t + 7 = -1 and get t alone on one side, follow these steps:
Step 1: Subtract 7 from both sides of the equation.
2t + 7 - 7 = -1 - 7
2t = -8
Step 2: Divide both sides of the equation by 2.
2t/2 = -8/2
t = -4
By subtracting 7 from both sides and then dividing by 2, you were able to isolate t and find that its value is -4.
