Answer:
252
Step-by-step explanation:
We can use the identity
LCM(a, b) = a * b / GCD(a, b)
GCD(28, 63) = GCD(4 * 7, 9 * 7) = 7
LCM(28, 63) = 28 * 63 / 7 = 28 * 9 = 252
It would be: -3t + 6 < 3
Subtract 6 from both sides,
-3t < -3
Divide by -3,
-3t/-3 > -3/-3 [sign changed 'cause we used -ve sign ]
t > 1
In short, Your Answer would be t > 1
