Answer:
<em>Multiply the bottom equation by -3/2 then add the equations.
</em>
<em>Multiply the top equation by-3. then add the equations
</em>
<em>
</em>
Step-by-step explanation:
Given the simultaneous equation
2x- 6y=6 ... 1
6x - 4y = 2 ... 2
To eliminate a variable, we have to make the coefficient of one of the variable to be the same.
Multiply equastion 1 by -3
-6x+18y= -18
6x - 4y = 2
Add the result:
-6x + 6x + 18y-4y = -18+2
18y-4y = -18+2
14y = -18
y = -9/7
Another way is to Multiply the bottom equation by -3/2 then add the equations.
Multiplying equation 2 by -3/2 will give;
6x(-3/2) - 4y(-3/2) = 2(-3/2)
-9x + 6y = -3
Add to equation 1;
2x- 6y=6
-9x + 2x + 0 = -3+6
-7x = 3
x = -3/7
Hence the correct two options are;
<em>Multiply the bottom equation by -3/2 then add the equations.
</em>
<em>Multiply the top equation by-3. then add the equations
</em>

Answer: Your answer is correct.
Explanation:
Use the marker gradations to identify the projected geometric shapes from the top, front and right side view as shown in the figure below.
All the gradation markings agree with your choice.

Answer:
(-3 ,2.5)
Step-by-step explanation:
midpoint formula is
x1+x2 y1+y2
(___ , _____ )
2 2
(-7,-2) -7 is x1 i.e the first x point and -2 is y1 1st y point
(1,7) 1 is x2 i.e the second x point and 7 is y2 the second y point
now we use input the numbers to the formula
-7+1 -2+7
(____ , --------)
2 2
we the signs are different you subtract and use sign of greater number
-6 5
__ , ___
2 2
Now you divide
and here is the ordered pair for midpoint.
(-3 ,2.5)
It’s
X=58, Y=32
Z=32
Because a triangle adds up to 180 deg.
