Answer:
No the soultion is not equal to 1 1/4
The solution to the given question is either 6 3/4 or 4 /27
Explanation:
Let
3(+9)=(4−7+7)x
27 = 4x
x= 27/4
x= 6 3/4 is the answer
or
Let
3(+9) x=(4−7+7)
27x = 4
x= 4/27
The plus sign inside the bracket indicates that 3 is multiplied with positive nine and -7 and +7 are cancelled and 4 is left behind.
If x is on the left side the answer will be 6 3/4 and if it is on the right side the answer is 4/27 .
In both cases the answer is not equal to 5/4 .
5/4 means 1 1/4 which is not equal to either 6 3/4 or 4/27
