Solve the following equation simultaneously 2a-3b+10=0, 10a+6b=8​
tia_tia [17]

2a -3b +10 =0\\\\10a+ 6b -8 =0\\\\\text{Using cross multiplication method}\\\\\\ \dfrac a{(-3)(-8)  - 6(10)} = \dfrac b{10(10) - 2(-8)} = \dfrac 1{ 2(6) - (-3)(10)}\\\\\\\implies  \dfrac a{24-60} = \dfrac b{100+16} = \dfrac 1{12+30}\\\\\\\\\implies -\dfrac {a}{36} = \dfrac b{116} = \dfrac 1{42}\\\\\\\text{Hence}\\\\a = - \dfrac{36}{42} = -\dfrac 67 \\\\\\ b= \dfrac{116}{42} = \dfrac{58}{21}

The answer choices are -3, 3/2, 3, and -12/5.<br> thanks in advance!! :)
BabaBlast [244]

Answer:

<em>(C). {3} </em>

Step-by-step explanation:

\frac{x}{2(x+1)} = \frac{-2x}{4(x+1)} + \frac{2x-3}{x+1} ( x ≠ - 1 )

\frac{x}{2(x+1)} - \frac{2x-3}{x+1} + \frac{x}{2(x+1)} = 0

\frac{2x-3}{x+1} - \frac{x}{(x+1)} = 0

\frac{x-3}{x+1} = 0 ⇒ <em>x = 3</em>
