Question

solve the system of equations below by graphing both equations with a pencil and paper. what is the solution y = x - 1 y = 1/2x + 1

Answer 1

(4,3)

Explanation:

`(x-1) = (1)/(2)x +1`

`(x-(1)/(2)x)-(-1+1)=((1)/(2)x-(1)/(2)x)+(1+1)`

`((1)/(2)x/(1)/(2))=(2/(1)/(2))`

`x=4`

`y=(4)-1`

`y=3`

`y=(1)/(2)(4)+1`

`y=2+1`

`y=3`
