Step-by-step explanation:
x=
(6b−10a)
(3b−5a)
y =\frac{(3b-5a)}{(6b-10a)}y=
(6b−10a)
(3b−5a)
Step-by-step explanation:
\begin{lgathered}Given \\ ax+by=\frac{a+b}{2}\end{lgathered}
Given
ax+by=
2
a+b
\implies 2ax+2by=a+b--(1)⟹2ax+2by=a+b−−(1)
\begin{lgathered}and\\3x+5y=4 ---(2)\end{lgathered}
and
3x+5y=4−−−(2)
Multiply equation (1) by 3 ,and equation (2) by 2a , we get
6ax+6by=3a+3b ---(3)
6ax+10ay = 8a -----(4)
Subtract equation (4) from equation (3), we get
(6b-10a)y = 3a+3b-8a
=> (6b-10a)y = 3b-5a
\implies y = \frac{3b-5a}{6b-10a}--(5)⟹y=
6b−10a
3b−5a
−−(5)
\begin{lgathered}Now, \\Substitute \:value \: of \: y\\ \: in \: equation \: (2), \: we \: get\end{lgathered}
Now,
Substitutevalueofy
inequation(2),weget
3x+\frac{5(3b-5a)}{6b-10a}=43x+
6b−10a
5(3b−5a)
=4
\implies 3x = 4 -\frac{5(3b-5a)}{6b-10a}⟹3x=4−
6b−10a
5(3b−5a)
\implies 3x = 4 -\frac{15b-25a)}{6b-10a}⟹3x=4−
6b−10a
15b−25a)
\implies 3x = \frac{24b-40a-15b+25a}{6b-10a}⟹3x=
6b−10a
24b−40a−15b+25a
\implies 3x=\frac{9b-15a}{6b-10a}⟹3x=
6b−10a
9b−15a
\implies x = \frac{3(3b-5a)}{3(6b-10a)}⟹x=
3(6b−10a)
3(3b−5a)
\implies x = \frac{(3b-5a)}{(6b-10a)}---(6)⟹x=
(6b−10a)
(3b−5a)
−−−(6)
Therefore,
x = \frac{(3b-5a)}{(6b-10a)}x=
(6b−10a)
(3b−5a)
y =\frac{(3b-5a)}{(6b-10a)}y=
(6b−10a)
(3b−5a)
