Question

if x=1 ,y=1 is a solution of the equation 5x+ by =7,find the value of b​

Answer 1

Step-by-step explanation:

put the values of x and y in the equation

5*1 + b*1 = 7

5 + 1b = 7

1b = 7-5

b = 2. ( as 1b is equals to b only)

hence, the value of b is 2

hope it is helpful :)

Answer 2

✬ The value of b is 2 ✬.

Step-by-step explanation:

➽ 5x + by = 7

• x = 1,y = 1

➽5(1)+b(1) = 7

➽ 5 + b = 7

➽ b = 7 - 5

➽ b = 2
