Answer: t=-20 and -20=t. *The answer must be have negative sign.*
Explanation:
multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
multiply by 5 both sides of an equation.
5*3/5t=5(-12)
simplify by equation.
3t=-60
divide by 3 both sides of an equation.
3t/3=-60/3
simplify by equation.
60/3=20
20*3=60
60/20=3
3*20=60
t=-20
Hope this helps!
Thanks!
Have a great day!
