Add the two equations:

2x + 4y = 16

-2x - 3y = -6

2x + -2x = 0

4y -3y = y

16-6 = 10

When you add the equations you get y = 10

Now you have a value for y, use the first equation to solve for x:

2x + 4(10) = 16

2x + 40 = 16

Subtract 40 from both sides:

2x = -24

Divide both sides by 2

X = -12

Answer: x = -12 and y = 10

Answer:

x = 12 y = 10

Step-by-step explanation:

Okay, Lets Solve!

You have to change the equations up to where if you line the equations up and added or subtracted, one of the variables will be eliminated:

:[tex]2x + 4y = 16[/tex]

[tex]-2x - 3y = -6\\[/tex]

These are our 2 equations! Now, to start, let's add these 2 equations up:

This is what you will get: [tex]y=10[/tex]

Now that we know what y is, lets substitute that in one of our equations!

I am going to choose the 1st one : [tex]2x + (4)(10) = 16[/tex]

Now, we solve for x!

[tex]2x + (4)(10) = 16\\= 2x + 40 = 16\\= 2x = -24\\= x = -12[/tex]

There you go! rlly hope this helps!! :)
