Y = -6.
-2(7)-2y=-2

-14-2y=-2

you need to move -14 to the other side by canceling out -14 with +14, and add +14 to -2, giving you -2y=12. -2/12=-6

Solve for x: 14-14x^1/3 =2

zmey [24]

Answer: 216/343 or 0.6297

Step-by-step explanation:

$14-14x^{1/3} = 2\\14 -2 = 14x^{1/3}\\12 = 14x^{1/3}\\\frac{12}{14} =x^{1/3}\\\frac{6}{7} =x^{1/3}\\(\frac{6}{7})^3 =(x^{1/3})^3\\\frac{6^3}{7^3} =x\\\\\frac{216}{343} = 0.629737609 = x$
