Question

Please help me with this i really need help I BEGGGG

Answer 1

The values of x and y that satisfy the equation
`$10=x+2 y$` are

(1) when
`x=0` ⇒
`y=5`

(2) when
`x=2` ⇒
`y=4`

(3) when
`y=0` ⇒
`x=10`

Step-by-step explanation:

The given equation is
`$10=x+2 y$`

Now, we shall determine the values of x and y such that the values satisfy the equation.

(1) To find the value of y, when
`x=0`

Substituting,
`x=0` in the equation
`$10=x+2 y$`, we get,

`10=2y\\5 \ =y`

Thus, the value of y when
`x=0` is 5.

(2) To find the value of both x and y.

Since, it is given that we need to choose on our own the x-value or y-value, let us substitute
`x=2` in the equation
`$10=x+2 y$`, we have,

`10=2+2 y\\8 \ =2y\\4 \ =y`

Thus, the value of y when
`x=2` is 4

(3) To find the value of x when
`y=0`

Substituting
`y=0` in the equation
`$10=x+2 y$`, we get,

`10=x+2(0)\\10=x`

Thus, the value of x when
`y=0` is 10.
