Question

What is another solution of the equation x+y=7

Answer 1

There are multiple solutions to x+y=7, here are a few. x=1 and y=6:1+6=7, x=2 and y=5: 2+5=7, x=3 and y=4: 3+4=7, and one more, x= 0 and y=7: 0+7=7. Hope this helps.

Answer 2

Solution is
`(1,6)`

Explanation:

An equation of the form
`ax+by+c=0` where
`a,b,c` are coefficients and
`x,y` are variables is a linear equation in two variables This equation is linear as here power of variables
`x,y` is 1. Also, this equation contains two variables
`x,y`. Solution of this equation refers to the values of
`x,y` which satisfies this equation. We can say
`\left ( x_0,y_0 \right )` satisfies the equation
`ax+by+c=0` if
`ax_0+by_0+c=0` .

Given:
`x+y=7`

Take
`(x_0,y_0)=(1,6)`

`(x_0,y_0)` satisfies this equation if
`x_0+y_0=7`

L.H.S

`x_0+y_0=1+6=7`

R.HS

7

As
`L.H.S=R.H.S` , so , point
`\left ( x_0,y_0 \right )=\left ( 1,6 \right )` satisfies this equation
