1. For three consecutive integers, when four times the third is subtracted from five times the first, the result is –4. Find the integers.
---
1st: x-1
2nd: x
3rd: x+1
Equation:
5(x-1)-4(x+1) = -4
5x-5-4x-4 = -4
x = 5
---
1st: x-1 = 4
2nd: x = 5
3rd: x+1 = 6
===================================
2. If six is added to three times a certain number, the result is 24. Find the number.
3x+6 = 24
3x = 18
x = 6
=======================
3. If two is subtracted from five times a certain number, the result is 38. Find the number.
5x-2 = 38
5x = 40
x = 8
------------------------
4. Nineteen is four larger than three times a certain number. Find the number.
19 = 3x+4
3x = 15
x = 5
