Question

Solve this system of equations, by graphing , First graph the equations, then type the solution??

Can you please help me with this hopefully you guys can help with my homework❣

Answer 1

Explanation:

Given:

{x+y=72x−y=2

Add the two equations to eliminate y and get:

3x=9

Divide both sides by 3 to find:

x=3

Then:

y=7−x=7−3=4

Answer 2

Answer:

$\red{ \boxed{\texttt{Answer}}}$

So, what you wanna try to do is to try to make sure all of your equations are in y= mx + b form. While y=-1/4x-1 is in that form, 3x+2y=8 is not. This means we have to try to solve for y.

3x + 2y = 8

-3x -3x

2y= (-3x + 8)

/2 /2

y= -3/2x +4
