Answer:

-12

Step-by-step explanation:

To solve for this question, you have to isolate the variable u. To do this, divide both sides by 7/4 to isolate the u. Then your equation should be u= -21 divided by 7/4. This would simplify to -21 times 4/7. This would get you -12. Hope this helps :)

Find the solution of the system of equations.<br><br> x-y=-3<br>-8x+y=45
mezya [45]

Answer:

x = 17, y = 28

Step-by-step explanation:

1. Isolate for x in "x - y = -3, -8":

x - y+y = -3, -8+y

x = -11 + y

2. Substitute "x = -11 + y" in for x in the second expression:

-11 + y + y = 45

3. Simplify:

-11 + 2y = 45

4. Isolate y:

-11+11 +2y = 45+11

2y = 56

\frac{2y}{2} = \frac{56}{2}

y = 28

5. Substitute the new y-value into the first equation:

x = -11 + 28

x = 17

hope this helps!

In-s [12.5K]
Answer: B

Explanation: an isosceles triangle has 2 sides that are the same, so if the base angles are both 34° then you can multiply that by 2 to get 68°. After that you know that you're still missing one of the angles so that missing angle is x. The equation you can set up to solve for x is the following: 68° + x° = 180°

Hope this helped! :)
