Answer:

2x = -4

Step-by-step explanation:

x is 'a number'

If you wanted to solve your equation:

2x = -4

2x/2 = -4/2 Divide both sides by 2

(To get x alone)

x=-2

X = y^2 - 1

ohaa [14]

Answer: The correct option is (B) $2y^2-y-6=0.$

Step-by-step explanation: We are given the following system of equations :

$x=y^2-1~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\2x-y=4~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)$

We are to find the equation that could be the result of using substitution to solve the above system.

Substituting the value of x from equation (i) in equation (ii), we get

$2x-y=4\\\\\Rightarrow 2(y^2-1)-y=4\\\\\Rightarrow 2y^2-2-y=4\\\\\Rightarrow 2y^2-y-2-4=0\\\\\Rightarrow 2y^2-y-6=0.$

Thus, the required equation is $2y^2-y-6=0.$

Option (B) is CORRECT.
