For the equation to work, you have to have the same number on both sides of the equal sign

so to find ?, you can do:

13 - 2 = 12 - ?       Simplify

11 = 12 - ?       Subtract 12 on both sides

-1 = - ?     Multiply -1 on both sides

1 = ?

3x+2y=0 <br> 9x-24=2y<br><br> How can you order a ladder?
natulia [17]
Answer: x=2 and y=-3


Because:
Substitute the second equation for 2y into the first equation
3x + 9x - 24 = 0
12x - 24 = 0
12x = 24
x = 2

3x + 2y = 0
(3x2) + 2y = 0
6 + 2y = 0
2y = - 6
y = - 3

PLEASE HELP IM TAKING THE TEXT NOW!!!!!!!!!!!!!!!!!<br> Solve for x and y<br> 3x+y=6<br> x+y=2
Over [174]

Answer:

I'm glad you asked!

Step-by-step explanation:

Let's solve for y first.

3x + y = 6

Step 1: Add -3x to both sides.

3x+y+-3x=6+-3x

y=-3x+6

Answer:

y=-3x+6

Now let's solve for x

3x+y=6

Step 1: Add -y to both sides.

3x+y+-y=6+-y

3x=-y+6

Step 2: Divide both sides by 3.

\frac{3x}{3} =\frac{-y+6}{3}

x=\frac{-1}{3} y+2

Answer:

x=\frac{-1}{3} y+2
