Answer 3

It seems like there might be a typo or formatting error in your equation. Let me try to correct it:

Original Equation: 9)-7/8+(-1/4)=10)-7/12+(8 1/6)

I'll correct it to this:

9 - 7/8 + (-1/4) = 10 - 7/12 + 8 1/6

Now, let's solve this equation step by step:

First, simplify each side separately:

On the left side: 9 - 7/8 - 1/4

On the right side: 10 - 7/12 + 8 1/6

Next, find a common denominator for the fractions on each side:

On the left side, the common denominator is 8: (72/8) - (7/8) - (2/8)

On the right side, the common denominator is 12: (120/12) - (7/12) + (8 2/12)

Now, perform the calculations:

On the left side: (72 - 7 - 2)/8 (63/8)

On the right side: (120 - 7 + 8 2)/12 (121/12)

So, the simplified equation is now:

(63/8) = (121/12)

To compare these two fractions, we need to find a common denominator. In this case, the common denominator is 24:

(63/8) * (3/3) = (189/24) (121/12) * (2/2) = (242/24)

Now, the equation becomes:

(189/24) = (242/24)

Since the numerators on both sides are equal, the fractions are equal. Therefore, the solution to the equation is:

189/24 = 242/24

Or, if you simplify further:

189/24 = 242/24

Both sides of the equation are equal, so there is no solution to this equation.
