7x+2y=5;13x+14y=-1 Solution : {x,y} = {1,-1} System of Linear Equations entered : [1] 7x + 2y = 5 [2] 13x + 14y = -1 Graphic Representation of the Equations : 2y + 7x = 5 14y + 13x = -1 Solve by Substitution :

// Solve equation [2] for the variable y

[2] 14y = -13x - 1 [2] y = -13x/14 - 1/14

// Plug this in for variable y in equation [1]

[1] 7x + 2•(-13x/14-1/14) = 5 [1] 36x/7 = 36/7 [1] 36x = 36

// Solve equation [1] for the variable x

[1] 36x = 36 [1] x = 1

// By now we know this much :

x = 1 y = -13x/14-1/14

// Use the x value to solve for y

y = -(13/14)(1)-1/14 = -1 Solution : {x,y} = {1,-1} Processing ends successfully

Which or the following is the radical expression of 4d3/8

stira [4]

Answer:

$\boxed{4 \sqrt[8]{ {d}^{3} } }$

Step-by-step explanation:

$= > 4 {d}^{ \frac{3}{8} } \\ \\ = > 4({d}^{3 \times \frac{1}{8} }) \\ \\ = > 4( {d}^{3} \times {d}^{ \frac{1}{8} } ) \\ \\ = > 4( {d}^{3} \times \sqrt[8]{d} ) \\ \\ = > 4 \sqrt[8]{ {d}^{3} }$
