Question

if x=1 and y=b is the solution of the equation x+3y=10 then find b​

Answer 1

Answer:

Here is your answer mate!

pls mark as brainliest and follow;-)

$x = 1 \: after \: puttng \: the \: value \: of \: x \: we \: get \\x + 3y = 10 \\ = 1 + 3y = 10 \\ = 3y = 10 - 1 \\ = 3y = 9 \\ = y = \frac{9}{3} \\ = y = 3 = b \\ beause \: it \: is \: given \: in \: the \: question \: that y = b$

Answer 2

Answer:

x = 1 after puttng the value of x we get

x + 3y = 10

= 1+ 3y = 10

= 3y = 10 – 1

= 3y = 9 =Y

9 /3 = Y

= =y=3= b

because it is given in the question .
