Find X such that: 7x + 24x = 25x

Vilka [71]

Answer:

$\boxed{ x = 0}$

Step-by-step explanation:

7x + 24x = 25 x

31 x = 25 x

Subtracting 25x to both sides

31x - 25x = 0

6x = 0

Dividing both sides by 6

=> x = 0

In the system of equations below, I want to eliminate the variable y.

Mekhanik [1.2K]

Answer:

(x,y)=(-1,1)

Step-by-step explanation:

Given that,

3x + 5y = 2 .....(1)

6x - 10y = -16 ....(2)

Finding the value of x from equation (1).

$x=\dfrac{2-5y}{3}$

Put the value of x in equation (2)

$6(\dfrac{2-5y}{3}) - 10y = -16\\\\2(2-5y)-10y=-16\\\\4-10y-10y=-16\\\\-20y=-16-4\\\\y=1$

Put the value of y in equation (1) :

$3x + 5(1) = 2\\\\3x=2-5\\\\3x=-3\\\\x=-1$

So, the solution of the equations is (-1,1).
