Add the numbers
24t3
24t3−3=0
Move the constant to the right-hand side and change its sign
24t3=0+3
Removing 0 doesn't change the value,so remove it from the expression
24t3=3
Divide both sides
2424t3=243
Divide the numbers
t3=243
Cancel out the common factor 3
t3=81
Take the 3-th root on both sides of the equation
3t3=381
Calculate
t=381
