Answer: 21
Step-by-step explanation:
Ok so first of all the numbers in the parentheses go first.
So 6 to the power of 2 (6^2) would be 6x6 which equals 36
50-36=14
After that you just keep rewriting the problem after every step.
Since the 3 is outside of the parentheses, you would multiply it with the 14
3x14=42
Finally 42÷ 2=21
3x (50 - 6^2) ÷ 2 =
3(14)÷ 2
42÷ 2= <u><em>21</em></u>

<u><em>Hope this helps (:</em></u>
<u><em>Btw sorry if it's a bit confusing but the answer is 21</em></u>
No this is to much work for something that is 5 points to do Na man but I hope this helps you in the future .
You can use the process elimination to solve. In other words, subtract or add the equations like normal.
5x + 2y = -15
+ 2x - 2y = -6
Because there is a 2y and -2y, we can add both equations to eliminate the y so that we can figure out what x is:
5x + 2x = 7x
2y + (-2y) = 0
-15 + (-6) = -21
We now have 7x = -21
Divide all by 7 to get x = -3
Plug in -3 to any of the two equations. I will use the second equation:
2(-3) - 2y = -6
-6 - 2y = -6
-2y = 0
y = 0
This means that the solution to the system of equations is (-3, 0) in the form of (x, y).
