Answer:
There are an infinite number of solutions.
Step-by-step explanation:
An equation with 2 unknowns give an infinite amount of solutions, here is just one of the many:
Let y= 3 ( y can be any number)
(3) + 1 = -4x
4 = -4x
x = -4/4
x= -1
(x;y) = (-1;3)
Generally x and y can be any number, just let x or y be any number, then find the other variable based on the value of the number u assumed.
Answer:
Option B
Step-by-step explanation:

Lets open the brackets of L.H.S.

Lets substract q² from both the sides.


Lets divide both the sides by q.


Answer:
x
=
26
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
X subtracted from y means y-x
(4x^2-4x+3)-(2x^2-6x-4)
4x^2-4x+3-2x^2+6x+4
4x^2-2x^2-4x+6x+3+4=
2x^2+2x+7
Answer:
x = -25/13
Step-by-step explanation:
Subtract 41 from 16 and divide the difference by 13
