I AM TRYING TO SOLVE A SYSTEM OF EQUATIONS BY GRAPHING AND CAN GET THIS ONE.

3x + y = 2
4y = 12 - 12x

HOW DO YOU DO THIS?

• algebra -

Graph each Eq; the point where they intersect is the solution. Then verify
your solution by solving them mathematically.

Eq1: 3x + y = 2.
(-2,8), (0,2), (2,-4).

Eq2: 12x + 4y = 12.
Divide both sides by 4:
3x + y = 3.
(-2,9), (0,3), (2,-3).

Use the points given or any convenient points.

NOTE: The 2 Eqs have equal slopes. Therefore, they do not intersect and
there are no solution. Be sure to do
the graphs anyway.

m1 = -A/B = -3/1 = -3.
m2 = -A/B = -3/1 = -3.
