S 4x - 10y = -3<br> 112x + 5y = 12<br> What is the value of x in the solution in fraction form

Afina-wow [57]

Answer:

x = 21 / 228

Step-by-step explanation:

4x - 10y = - 3 -----> equation 1

112x + 5y = 12 -----> equation 2

Multiply 2 on both sides in the equation 2,

2 ( 112x + 5y = 12 )

224x + 10y = 24 -----> equation 3

Add equations 1 & 3,

4x - 10y = - 3

224x + 10y = 24

$f(x)=-4\sqrt{x}-1;\ x\geq0\\\\y=-4\sqrt{x}-1\\\\\text{solve for x}\\\\-4\sqrt{x}-1=y\ \ \ \ |+1\\\\-4\sqrt{x}=y+1\ \ \ \ |:(-4)}\\\\\sqrt{x}=-\dfrac{y+1}{4}\to y+1\leq0\to y\leq-1\\\\\text{square both sides}\\\\x=\dfrac{(y+1)^2}{4^2}\\\\x=\dfrac{(y+1)^2}{16}$
