Question

Solve -2t + 5 ≥ -7.

Answer 1

It's just like any other equation. You want to try and isolate t by itself. So you want to subtract any numbers to the opposite side then divide any coefficients that are with the t. The only difference with inequalities is that when you divide by a negative number you swich the inequality, i.e. > becomes < and vice versa.

Answer 2

Isolate for t
-2t+5≥-7
subtract 5 for both sides
-2t≥-12
divide both sides by -2
t≤6
the greater than or equal too sign flips when u divide by a negative number.
