Solve, using the substitution method.

4x + 2y = 11
x – 2 = – 2y

Question

Solve, using the substitution method.
 
4x + 2y = 11
x – 2 = – 2y

anonymous · Answer

x – 2 = – 2y
Solve for $x$.
$$x = -2y + 2$$

anonymous · Answer

Now input that value into the first equation.

anonymous · Answer

$$4-2y + 2 + 2y = 11$$
Move all the like terms to one side.

@zobobozo 
Can you do that?

anonymous · Answer

anonymous · Answer

Wait, sorry forgot the round brackets...
$$4(-2y + 2) + 2y = 11$$

anonymous · Answer

Is that what you got?
Odd I got:
$$x = 3,~y = \dfrac{-1}{2}$$

anonymous · Answer

$$4(-2y + 2) + 2y = 11$$
Simplifies to:
$$y = \dfrac{-1}{2}$$

anonymous · Answer

Then:
$$x – 2 = – 2y$$
Input -1/2:
$$x – 2 = – 2\dfrac{-1}{2}$$
Simplifies to:
$$x = 3$$

anonymous · Answer

no its 3 and -1/2

anonymous · Answer

Uh, I said that?
$$x = 3$$
$$y = \dfrac{-1}{2}$$
If you wanted to write that in a pair it would look like:
$$3, \dfrac{-1}{2}$$
