Deepak wrote out the steps to his solution of the equation 5/2-3x-5+4x = -7/4
step 1: 5/2-5+4x-3x=-7/4
step 2: -5/2+x+-7/4
step 3: -5/2+5/2+x = -7/4+10/4
step 4: x = 3/4which step has an incorrect instruction?

Step 2

Step-by-step explanation:

The given equation is:

Simplifying the above equation, we get

Step 1. Rewriting the like terms, we get

Step 2. Adding and subtracting the like terms, we have

(which is the incorrect step in the already given proof)

Step 3. Adding on both the sides, we get

( can be written as )

Step 4. Solving the above equation, we get

Thus, the step 2 is incorrect in the given proof.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
