Answer:

x=4

Step-by-step explanation:

6x-3=21

+3 +3 add three to both sides to get the coefficient on its own side

6x=24 (whenever we do something to one side, we do it to the other.)

÷6 ÷6 divide both sides by 6 to get our variable (x) alone

x=4 6x/6=x 24/6=4

6x-3=21

6x-3(+3)=21(+3) *to cancel 3 out & what
you do to something
on one side of the
equal side you need
to do to the other*

6x=24

6x(divide 6)=24 (divide 6) *to cancel the
6 out,
because you
want x by
itself

x = 4

<h3>What is Units conversion?</h3>

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

As it is given that one gram is equivalent to 0.035273 ounces, while 1 pound is equal to 16 ounces. Therefore, if we convert 0.45 pounds to grams,

Pounds to Ounces

$\rm 1\ pound = 16\ ounces\\\\0.45\ pounds = 0.45 \times 16 = 7.2\ ounces$
