Solve linear equations 12x+5y=7 and x+y=7 using Graphical Method

`12x+5y=7`

`x+y=7`

The point of intersection of the linear equations
Consider `12x+5y=7`

`x`-intercept: put `y = 0,` we get `x = 0.5833` `:. A(0.5833,0)`

`y`-intercept: put `x = 0,` we get `y = 1.4` `:. B(0,1.4)`


Consider `x+y=7`

`x`-intercept: put `y = 0,` we get `x = 7` `:. C(7,0)`

`y`-intercept: put `x = 0,` we get `y = 7` `:. D(0,7)`

Intersection Point = `P(-4,11)`
