Answer:
No, but x = 4
Step-by-step explanation:
3(7) + 8 - 7 = 5(7) - 4
21 + 8 - 7 = 22
22 = 35 - 4
22 = 31
It is not
How this equation may work is by subtracting the numbers by each side
3x + 8 - x = 2x + 8
2x + 8 = 5x - 4
-8 -8
2x = 5x - 12
-5x -5x
-3x = -12
x = 4
Question: The sum of 10 and 5 times a number is 25. Find the number.
Answer: x = 3
10 + 5x = 25
5x = 25 - 10
5x = 15
x = 3
-24y = -384, y would equal 16.
