Answer 3

To solve the equation, let's break it down step by step.

Step 1: Simplify the equation

640/700 - (× + 250/700) = 50/700

Step 2: Simplify the fractions

640/700 = 32/35 250/700 = 5/14 50/700 = 1/14

Now the equation becomes:

32/35 - (× + 5/14) = 1/14

Step 3: Distribute the negative sign to the expression inside the parentheses

32/35 - × - 5/14 = 1/14

Step 4: Find a common denominator

The common denominator for 35 and 14 is 70. Multiply the numerators and denominators accordingly:

32/35 - × - (5/14) * (5/5) = 1/14

32/35 - × - 25/70 = 1/14

Step 5: Combine the fractions

Multiply the fractions and subtract:

32/35 + 25/70 = × + 1/14

64/70 + 25/70 = × + 1/14

89/70 = × + 1/14

Step 6: Simplify the equation further

89/70 = × + 1/14

Now, let's isolate × by subtracting 1/14 from both sides:

89/70 - 1/14 = × + 1/14 - 1/14

89/70 - 1/14 = ×

To find a common denominator, multiply the numerators and denominators accordingly:

127/70 = ×

Therefore, the value of × is 127/70.
