Answer:

x/2 + 21 = 36

First we get rid of constants to isolate the variable.

In order to do that we must do the inverse operation.

Inverse operation of addition is subtraction.

-21 -21(subtracting 21 from both sides, whatever we do to the left side we do it to the right side too)

x/2 = 15

inverse property of division is multiplication

x2 x2

X = 30

Find the lcd of the pair of expressions

STALIN [3.7K]

$\frac{2}{7} {x}^{10} {y}^{4} \: and \: \frac{2}{14} {x}^{8} {y}^{7} \\ lcd = 14 {x}^{10} {y}^{7}$
Answer is
$14 {x}^{10} {y}^{7}$

When it's powered numbers, remember to choose the one with the largest power. For example,
${x}^{10}$
And
${x}^{8}$
Choose 10, same goes to y, where you choose 7 not 4 since 7 is larger.

Hope this helps. - M
