# How to solve the system of equations 8x-y=29 and 2x+y= 11 by graphing?

$x = 4 , y = 3$

#### Explanation:

We need to plot the straight lines: $8 x - y = 29$ & $2 x + y = 11$

Mathematical solution: Adding both the given linear equations, we get

$8 x - y + 2 x + y = 29 + 11$

$10 x = 40$

$x = 4$

$\setminus \therefore y = 8 x - 29 = 8 \left(4\right) - 29 = 3$

$x = 4 , y = 3$
