Solve this system by graphing and then find an exact Solution by using substitution or elimination.
X - 4y = -8
3x + y = 6
Put equations in the slope intercept form
-4y = -x - 8
Divide equation by -4
y = + 2
and
y = -3x + 6
Graph these two equations
:
Using elimination
:
multiply the 2nd equation by 4, add to the 1st equation
x - 4y = -8
12x+4y = 24
------------------
13x = 16
x =
:
Find y using equation y = -3x + 6
y = -3(16/13) + 6
y = +
y =
