When x-y=3 work out the value of y-x

GalinKa [24]

The value of y-x is (-3)

<u>Solution:</u>

Given: The value of x-y=3

To find: The value of y-x

$\bold{x-y=3\rightarrow (1)}$

Let's multiply the equation (1) by (- 1) on both sides,

$\Rightarrow\bold{(x - y)\times(- 1) = 3\times(- 1)}$

$\Rightarrow\bold{-(x-y)=-3}$

On multiplying the sign,

$\Rightarrow\bold{(-x+y)=-3}$

The above equation can also be written as,

$\Rightarrow\bold{y-x=-3\rightarrow \text{(The required equation)}}$

<u>Multiplication of signs:</u>

$\Rightarrow( + )\times( + ) = ( + )$

$\Rightarrow( + )\times( - ) = ( - )$

$\Rightarrow( - )\times( + ) = ( - )$

$\Rightarrow( - )\times( - ) = ( + )$

In simpler terms, when we multiply two integers with the same signs, the result is always positive and when we multiply two integers with different signs, the result is always negative.

5x +1 = -3+10x how do you solve this

Natali5045456 [20]

Answer:

x = 4/5

Step-by-step explanation:

Group like terms together. Start by subtracting 1 from both sides, obtaining

5x = -4 + 10x.

Then combine the x terms, obtaining 4 = 5x.

Solving for x by dividing both sides by 5, we get x = 4/5.
