For the first one, I will solve for t. s + 2t = 6, first we isolate the t variable, 2t = -s + 6, divide both sides by 2, t = -s/2 + 3, < There's your answer for 1!
Here's the second one, 3s - 2t = 2, subtract 3s from both sides, -2t = 2 - 3s, divide both sides by -2, t = -1 + 3s/2 < There's your second answer!
