<u>Part 1)</u> we have
------> equation A
------> equation B
Substitute the equation B in equation A
![5[12-3y]+2y=16](https://tex.z-dn.net/?f=5%5B12-3y%5D%2B2y%3D16)
Find the value of x
the best approximation is the point 
therefore
<u>the answer Part 1) is the option C</u>
<u>Part 2) </u>we have
------> equation A
------> equation B
equate equation A and equation B
Find the value of y
the solution is the point 
therefore
<u>the answer Part 2) is </u>
Answer:
1x
Step-by-step explanation:
12x-9= 3x.
1/3 of 3 is 1.
So therefore the answer is 1x.
The point-slope form:
We have the point (1, 6) and the slope m = 7/3. Substitute:
<em>use distributive property</em>
<em>add 6 to both sides</em>
<em>multiply both sides by 3</em>
<em>subtract 7x from both sides</em>
<em>change the signs</em>
Answer:
point-slope form:
slope-intercept form:
standard form:
Answer:21
Step-by-step explanation: you multiply f times x to equal 21
