Answer:
one num = 6
another = 24
Step-by-step explanation:
One number = x
Another = 4x
Difference = 18
4x - x = 18
3x = 18 ; x = 18/3 = 6
Answer:
x=4
Step-by-step explanation:
here's our equation: 3x=x+8
Our goal: to isolate x onto one side with nothing else on that side.
x is on both sides; we can subtract x from both sides to make the variables and numbers be on different sides
2x=8
Now we can divide by 2
x=4
Hope this helps! :)
