One solution was found : t ≤ -13 (number 4)
Pull out like factors :
-3t - 39 = -3 • (t + 13)
Divide both sides by -3
Remember to flip the inequality sign:
Solve Basic Inequality :
Subtract 13 from both sides to get t≤−13
The solution to a system of linear equations is (0, 4). One of the linear equations in the system is y = 8.1 +4.the answer is 12.1
