Answer 2

To solve the equation 2 2/9x + (x / 2 1/7) = 1210, we need to find the value of x.

First, let's simplify the equation by converting the mixed numbers to improper fractions:

2 2/9x + (x / 2 1/7) = 1210

2 2/9 can be written as (2 * 9 + 2) / 9 = 20/9.

2 1/7 can be written as (2 * 7 + 1) / 7 = 15/7.

Now, our equation becomes:

(20/9)x + (x / 15/7) = 1210

Next, let's simplify further by multiplying both sides of the equation by the least common multiple (LCM) of 9 and 7 to get rid of the fractions:

LCM(9, 7) = 63

Multiply every term by 63:

63 * [(20/9)x] + 63 * [(x / 15/7)] = 63 * 1210

Now, simplify each term:

(63 * 20/9)x + (63 * 7/15)x = 76330

Now, we can simplify the fractions:

(7 * 20)x + (3 * 7)x = 76330

140x + 21x = 76330

Combine like terms:

161x = 76330

Now, isolate x by dividing both sides by 161:

x = 76330 / 161

x ≈ 474.54

So, the approximate value of x that satisfies the equation is x ≈ 474.54.
