Answer:
t=7 or t=-7
Explanation:
To solve for t, we need to get t alone. To do this, perform the opposite of what is being done to the equation. Keep in mind, everything must be performed to both sides.
t^2=49
t is being squared. The opposite of squared is the square root. Take the square root of both sides.
√t^2=√49
t=√49
t=±7
So, t is equal to 7 or -7
