Equivalent equations help you to knock out the <span> choices and solve the problems more easier.
for example
</span>x + 6y = 8
<span>2x + 4y = 8
</span>multiply first equation to get rid of from x
2x+12y=16
2x+4y=8
now subtract second equation from first
8y=8
y=1
now put value of y in seond equation
2x+4(1)=8
2x=8-4
2x=4
x=2
hence,
<span>equivalent equations help you to solve a system of equations</span>
Using addition or multiplication, Teresa has twice a number of wood as Samuel.
According to the question,
Teresa needs twice as many feet of wood as Samuel in order to find the number of pieces of wood Teresa need only if we add the number Teresa has by itself or multiply it by 2.
Hence, we need to do only multiply it by 2

X=12/11 for the first one
Answer:
the answer is 6x.
Step-by-step explanation:
Answer
Option (A) is correct .
Reason
The formula for the slope.
As given
Line AB contains (0, 4) and (1, 6) .
put in the slope formula
Slope of the AB is 2.
As given
Line CD contains points (2, 10) and (−1, 4).
put in the slope formula
Slope = 2
Slope of the CD is 2.
As the slope of the AB contains (0, 4) and (1, 6) Line CD contains points (2, 10) and (−1, 4) is 2 .
Therefore the option (A) is correct i.e the lines are parallel because the slopes are the same.
