If you substitute the -8 in for y you will get -72
You can then add the 72 to the other side and get -8x=64
Dividing by -8 to both sides to get x alone will give you x
X=-8
Answer: It will be C, 5x + 2y = 6 is equivalent to y = -5/2x + 3
• y is vertically opposite to the one whose measure is 43º.
So,
y = 43º.
• x and y are supplementary angles:
x + y = 180º
x = 180º <span>– y
x = 180º </span><span>– 43º
x = 137</span><span>º.
</span><span>• z and x are vertically opposites.
So,
z = x
z = 137º<span> <</span></span>——<span><span>— this is the answer.</span>
I hope this helps. =)

So you need to isolate the N right?
So what you want to do is add -3/5 to both sides to remove it from the left side. making it
2n=5+3/5 now all you need to do it isolate the N by divinding it by 2 on each side
n=5+3/5
/2
the 5+3/5 is divided by 2.
so N equales 5+3/5----/2
Answer:
c, 4/3
Step-by-step explanation:
you need to isplate y so subtract 5 from both sides then divide both sides by 3, the coefficient of x is now 4/3 and x coefficient is the slope
