Answer:
6+x = 4x-18, 8
Step-by-step explanation:
6= 3x-18
24=3x
8=x
The equation is 6 + X = 4X - 18
The number is 12/5 or 2 2/5
Let the number be X
6 + X = 4X - 18
Add 4X to both sides of the equation
6 + X + 4X = 18 - 4X + 4X
6 + 5X = 18
Subtract 6 from both sides of the equation
6 - 6 + 5X = 18 - 6
5X = 12
Divide both sides by 5
5X/5 = 12/5
X = 2 2/5
The number is 2 2/5
