Question

The value of z in z/3 = 5 is ​

Answer 1

Answer:

$z\div 3 = 5 \\ z = 5 \times 3 \\ z = 15$

Answer 2

$\huge \bold \pink{solution}$

1stly we have to rearrange

$\small \bold \red { \frac{z}{3} - (5) = 0 }$

----------------------------------------------------------------

Step by Step explanation

___________________________________

$\huge \bold \pink{1 \: step}$

$\small\bold \red{we \: have \: to \: simplify \: \frac{z}{3}}$

$\small \bold \red{ \frac{z}{3} - 5 = 0}$

__________________________________

$\huge \bold \pink{2 \: step}$

Rewrite the whole as fraction using 3 denominator

$\small \bold \red{5 = \frac{5}{1} = \frac{5•3}{3} }$

Then we have to Add fractions that have common denominator:

$\small \bold \red{ \frac{z - (5•3)}{3} = \frac{z - 15}{3} }$

$\small \bold \red{ \frac{z - 15}{3} = 0}$

__________________________________

$\huge \bold \pink{ 3\: step }$

Now fraction has equals zero

$\small \bold \red{ \frac{z - 15}{3} •3 = 0•3}$

now equation takes shape like this

$\small \bold \red{z - 15 = 0}$

Now we have to solve single variable equation

$\small \bold \red{z - 15 = 0}$

Hence the solution is z=15
