The answer is 50y^2/49x . hope I helped
Answer: at end of explanation
Step-by-step explanation:
First simply operate the e's, so get common factor and (- 56 - 23)e = -24. This leaves you with -79e = -24. Then move the number multiplying e to dividing the other side, so e = -24 / -79, wich results in 0.8 period. So your result rounded to 2 decimal places is 0.89.
Answer: a pyramid
Step-by-step explanation:
When solving equations like these, our number one goal is to get x to be alone.
So given the equation lets go through it step by step.
3x - 5 = 10 + 7x (first step is to add 5 to both sides)
+ 5 = + 5 ( Now lets see what we have now)
3x = 15 + 7x ( We need the x to be alone! So lets subtract -7x from both sides.)
-7x = -7x ( now what do we have?)
-4x = 15 (okay divide both sides by 4 to isolate the x)
÷4 = ÷4 (now the 4's on the left side cancel out, and we solve on the right side)
x = 3.75
That's your answer :) Good Luck!
<span>x + 2y = 2
-x + 3y = 13
As the x-terms of these equations are already opposites, you can begin to solve by elimination by adding the equations together.
</span> x + 2y = 2
-x + 3y = 13
+___________
0 + 5y = 15
y = 3
Now that you have y, substitute its value, 3, into either equation to find x.
x + 2y = 2
x + 2(3) = 2
x + 6 = 2
x = -4
Lastly, check all work by substituting both x- and y-values into both original equations.
x + 2y = 2
-4 + 2(3) = 2
-4 + 6 = 2
2 = 2
-x + 3y = 13
-(-4) + 3(3) = 13
4 + 3(3) = 13
4 + 9 = 13
13 = 13
Answer:
x = -4
y = 3
(-4, 3)
