Solve for K

K=4

$K=4$

Steps for Solving Linear Equation

9 = \frac { K ( 2 ) ( 3 ) ^ { 2 } } { 8 }

$9=8K(2)(3)_{2} $

Multiply both sides by 8.

Multiply both sides by $8$.

9\times 8=K\times 2\times 3^{2}

$9×8=K×2×3_{2}$

Multiply 9 and 8 to get 72.

Multiply $9$ and $8$ to get $72$.

72=K\times 2\times 3^{2}

$72=K×2×3_{2}$

Calculate 3 to the power of 2 and get 9.

Calculate $3$ to the power of $2$ and get $9$.

72=K\times 2\times 9

$72=K×2×9$

Multiply 2 and 9 to get 18.

Multiply $2$ and $9$ to get $18$.

72=K\times 18

$72=K×18$

Swap sides so that all variable terms are on the left hand side.

Swap sides so that all variable terms are on the left hand side.

K\times 18=72

$K×18=72$

Divide both sides by 18.

Divide both sides by $18$.

K=\frac{72}{18}

$K=1872 $

Divide 72 by 18 to get 4.

Divide $72$ by $18$ to get $4$.

K=4
