Solve for t. −4t ≤ 48 t ≥ −12 t ≤ −12 t ≥ 12 t ≤ 12

Divide -4 from both sides to isolate the t
Note: When you DIVIDE a negative number (as in the negative number is located in the denominator when dividing) you must flip the sign.

−4t ≤ 48
-4t(/-4) ≤ 48(/-4)
t ≤ 48/-4
t ≥ -12

t ≥ -12 is your answer

hope this helps
