Answer: 40
Step-by-step explanation:
X = 6
28 = -2 - 5x
28 + 2 = 5x
30 = 5x
30/5 = 5x/5 (we divide by five on both side because we want x to be by itself)
6 = x

Answer: 3,4,5
Step-by-step explanation: a squared + b squared = c squared
A -> 3 squared is 9
B -> 4 squared is 16
9+16 is 25, so C has to be 25
C -> 5 squared is 25
So 3, 4, 5
1. Add 4x back into -2, you now have -4y=-4x-2. Add +4 from y and now you are at y=-4x+2 and this is the answer!
2. Add -9x back into -3, you now have -4y=9x-3. Add +4 from y and now you are at y=9x-7 and this is your answer!!
I hope this helped! Brainliest? :) -Raven❤️
