Question

if 3/x+4y=5 and y=1 then find value of x

Answer 1

Answer:

3 is the answer

Step-by-step explanation:

3/x+4=5

3/x=5-4=1

x=3

Answer 2

$\huge{ \underline{ \boxed{ \sf{ \green{Required \: AnsweR}}}}}$

• Given : The value of y = 1

• To find : The value of x.

$\sf{The\:Given\:Equation}$

$⟹ \frac{3}{x}+4y=5$

Substituting the value of y,

$\frac{3}{x} + 4 = 5$

Taking the LCM,

$\frac{3+4x}{x}=5$

3 + 4x = 5x

Taking 4x to the other side,

3 = 5x - 4x

$\boxed{x=3}$

$\boxed{\sf{\blue{VerificatioN}}}$

$\frac{3}{3}+4(1)=5$

Substituting the values of x & y,

$\frac{3}{3}+4(1)=5$

1 + 4 = 5

5 = 5

$\sf{Hence\:Proved!}$
