Question

$x + y + y3$
=43
what is yand x​

Answer 1

Answer:

$\sf \: finding \: value \: of \: x :$

$\sf \: x+y+y {}^{3} =43$

$\sf \: add \: {y}^{3} \: to \: both \: sides$

$\bf \: {y}^{3} + x + y + { -y }^{3} = 43 + { - y}^{3}$

$\sf \: x + y = { - y}^{3} + 43$

$\sf \: x+y+−y=−y {}^{3} +43+−y \\ </p><p></p><p> \sf \: x=− {y}^{3} −y+43 \qquad \qquad \qquad</p><p></p><p></p><p>$

$\bf answer : \sf{ x = - y}^{3} - y + 43$

$\sf \: now \: you \: can \: find \: the \: value \: of \: y$

HOPE IT HELPS.

Answer 2

Step-by-step explanation:

finding value of x:

$\sf \: x+y+y {}^{3} =43$

$\sf \: add \: {y}^{3} \: to \: both \: sides$

$\bf \: {y}^{3} + x + y + { -y }^{3} = 43 + { - y}^{3}y$

$\sf \: x + y = { - y}^{3}$

$\begin{gathered} \sf \: x+y+−y=−y {}^{3} +43+−y \\ \sf \: x=− {y}^{3} −y+43 \end{gathered}$

$\bf answer : \sf{ x = - y}^{3} - y + 43$

$\sf \: now \: you \: can \: find \: the \: value \: of \: y$
