Answer:
4 is the [ ] in whole part.
Explanation:
Given equation [(x-1)/3]=(x+3)/4
Let us first get rid denominators from both sides.
On cross multiplying both sides, we get
4(x-1) = 3(x+3)
4x-4 = 3x+9
Adding 4 on both sides, we get
4x-4+4 = 3x+9+4
4x = 3x +13
Subtracting 3x on both sides, we get
4x-3x = 3x-3x +13
x = 13.
Now, we need to find the value of [ ] fraction We have [(x-1)/3] in given equation.
Plugging x= 13 in (x-1)/3, we get
13-1/3 = 12/3 = 4.
Therefore, 4 is the [ ] in whole part.
