y = 12. It's the transitive property. y = 12 = 3x.
5x + 3 = -12 5x =-12-3 =-15 x = -3
12 x 3 = 36

3t + 7 = 2t - 5 3t = 2t - 12 t = -12
9 + t/12 = -3 t/12 = -12 t = -144
t=3/2 or t=2 1/2

I am going to guess that you mean: Find t when (√(t + 12)) - t = 0. Then, √(t + 12) = t; t + 12 = t²; (squaring both sides) t² - t - 12 = 0; (t - 4)(t + 3) = 0; and t = 4 or -3. We'd best check both results, because we squared both sides at an earlier stage, which introduces an ambiguity and, probably, an extraneous answer: Our original equation is seen to hold, for t = 4: √(4 + 12)) - 4 = √16 - 4 = 4 - 4 = 0. However, it does not hold, for t = -3. √(-3 + 12)) + 3 = √9 + 3 = 3 + 3 = 6 ≠ 0. Thus, the answer is that t = 4.
t=-10

If you mean t(t+7) = 4(3+2t), then it is factored. If you meant solve for 't', then the solution is t = t2 - 12.
t in this problem equals -3. 4t- 8+ 25= 5 -25 -25 4t- 8= -20 +8 +8 4t= -12 /4 /4 t= -3
6t 6(2) t=2 12 The answer is 12.
