Answer: easy peasy so your answer would be 4=(6x7)x12 so what you would do is take the first two and dived them your answer you want to dived it with your other numbers
Step-by-step explanation:
The number is 1
Step-by-step explanation:
Let x be the required number
Then according to given statement
Five times the difference of twice a number and seven is negative twenty-five.
Simplifying
Adding 35 on both sides
Dividing both sides by 10
Verification:
![5[2(1)-7] = -25\\5(2-7) = -25\\5(-5) = -25\\-25=-25](https://tex.z-dn.net/?f=5%5B2%281%29-7%5D%20%3D%20-25%5C%5C5%282-7%29%20%3D%20-25%5C%5C5%28-5%29%20%3D%20-25%5C%5C-25%3D-25)
Hence,
1 is the number

Answer:
(x, y) = (8, -3)
Step-by-step explanation:
You can substitute for x in the first equation:
3(-3y -1) +3y = 15
-6y = 18 . . . . . add 3 and simplify
y = -3 . . . . . . . divide by -6
x = -3(-3) -1 = 8 . . . . find x using the second equation
The solution to this system of equations is (x, y) = (8, -3).
2(4x - 9) =
2 * 4x - 2 * 9 =
8x - 18
