Question

necesito resolver ecuaciones:

(x+12):8=216

15.(X-7)+3³  11 = √144+ 7²

Answer 1

$(x+12) :8 = 216 \\ \\ (x+12) =216 * 8 \\ \\ x = 1728 - 12 \\ \\ \boxed{x=1716 } \\ \\ \\ 15(x-7)+3^3*11= \sqrt{144} + 7^2 \\ \\ 15x -105 + 27*11= 12 + 49 \\ \\ 15x-105 + 297 = 61 \\ \\ 15x = 61 - 297 + 105 \\ \\ \boxed{x = \frac{-131}{15} }$

Espero que te sirva, salu2!!!!
