Answer: D is the correct answer
Multiply the first equation by -2 to eliminate a variable so it becomes:
-12x+8y=48
4x-8y=-32
Add them together.
-8x=16
x=-2
Plug it in one equation.
6(2)-4y=-24
12-4y=-24
-4y=-12
y=3
Ordered pair is: (-2,3)
The first thing we are going to do is distribute:
=<span>4x+(6)(3x)+(6)(−2)
</span>=<span><span><span><span>4x</span>+<span>18x</span></span>+</span>−<span>12
</span></span>Second thing we are going to do is C<span>ombine Like Terms:
</span>=<span><span>4x+18x</span>+<span>−<span>12
=</span></span></span><span>(<span><span>4x</span>+<span>18x</span></span>)</span>+<span>(<span>−12</span><span>)
</span></span>And your final answer is:
<span>22x</span>+<span>−<span>12</span></span>
I hope this helps you! :)
