Question

1) To draw graph of 4x+6y=19, Find
Y y when x=1.
A)2
B)4
C)3
D)-3​

Answer 1

Answer:

3 If x=1 then y=3

Step-by-step explanation:

GivenLinearequationintwo

variablesxandyis4x+5y=19

Substitute \: x = 1 \: in \:the \: equation, \: we\:getSubstitutex=1intheequation,weget

\implies 4\times 1 + 5y = 19⟹4×1+5y=19

\implies 4 + 5y = 19⟹4+5y=19

\implies 5y = 19 - 4⟹5y=19−4

\implies 5y = 15⟹5y=15

\implies y = \frac{15}{5} = 3⟹y=

5

15

=3

Therefore.,

If \: x = 1 \: then \: y = 3Ifx=1theny=3
