Answer 2

Answer:

The value of b is 15.

Step-by-step explanation:

Given -

x = 5

y = 0

$3x + 5y = b$

To find out the value of b

$3x + 5y = b \: \: \: \: \: \: \: \: \: \: (1)$

Put the given values of x and y in these equation (1)

$3 \times 5 + 5 \times 0 = b$

When we multiply any number by 0 we get 0.

So,

$5 \times 0 = 0$

$3 \times 5 = 15$

By Putting these values equation becomes

$15 + 0 = b$

By adding any number to 0 we get that number.

So, By adding 15 and 0 we get

$b = 15$

Hence,

The value of b is 15.
