Answer:

Step 2 is incorrect

Step-by-step explanation:

Step 2 is incorrect

step 1: 3x + 15 = 2x + 35

step 2: subtract 2x from both sides

3x + 15 - 2x = 2x + 35 - 2x

x + 15 = 35

5 1/3 + x = 2 1/2. Use least common denominator or easiest common denominator. Please work out

Answer:

The answer is x = -17/6.

Step-by-step explanation:

Given:

5 1/3 + x = 2 1/2 . Using least common denominator.

Now, to solve the equation:

$5\frac{1}{3}+x=2\frac{1}{2}$

$=\frac{16}{3} +x=\frac{5}{2}$

Subtracting both sides from 16/3 we get:

$x=\frac{5}{2}- \frac{16}{3}$

Now, the least common denominator of 2 and 3 is 6.

So, we using this we calculate:

$x=\frac{5\times 3-16\times 2}{6}$

$x=\frac{15-32}{6}$

$x=\frac{-17}{6}$

Therefore, the answer is x = -17/6.
