Question

find the value of B, if x is equal to 5 and Y is equal to zero is a solution of the equation 3 X + 5 Y is equal to b​

Answer 1

Answer:

b=20

Step-by-step explanation:

x=5 and y=0

3x+5+y =b

3(5)+5+0=b

15+5+0=b

20=b

or

b=20

Answer 2

Given: x=5 and y=0 is solution for 3x+5y=b

Substituting x and y in the equation,

3×5+5×0=b

15=b

Hence the value of b is 15
