Question

----2
(3x +2) :7 + 1 =12



√x-1 +2 =12

Answer 1

$(3x^2+2):7 +1= 12 \\ \\ Seaparamos \ en \ t\'erminos \ y \ depejamos \\ \\ (3x^2+2):7 = 12-1 \\ \\ (3x^2+2) = 11*7 \\ \\ 3x^2+2 = 77-2 \\ \\ 3x^2 = 75 \\ \\ x^2= \frac{75}{3} \\ \\x= \pm \sqrt{25} \\ \\ x_1= +5 \qquad x_2= -5$

...........................................................................................................


$\sqrt{x-1} +2 =12 \\ \\ \sqrt{x-1} =12 -2\\ \\ x-1= 10^2 \\ \\ x= 100+1 \\ \\ \boxed{x= 101}$

espero que te sirva, salu2!!!!
