Answer:
3x - y = -28
Step-by-step explanation:
Given the equation y-4 = 3(x+8), distribute and simplify to get the Standard Form.
y-4 = 3(x+8)
y - 4 = 3x + 24
y = 3x + 28
-3x + y = 28
Standard form does not allow the coefficient of x to be negative so multiply the equation by -1.
3x - y = -28
3/5=12/x
reciprical of both sides
5/3=x/12
times twelve on both sides
x=20
- Let the smaller number be x and the bigger number be y.
- Therefore, 3x = 2y


- Therefore, the smaller number = 30 - 18 = 12
