Question

A note shows solving an equation. First line. 5 c minus 6 equals 4 minus 3 c. Second line. 2 c minus 6 equals 4. Third line. 2 c equals 10. Fourth line. c equals 5
In the third step, you should add $4$ to each side, not $6$ .
In the third step, you should add , 4, to each side, not , 6, .

In the third step, you should add $-6$ to each side, not $6$ .
In the third step, you should add , negative 6, to each side, not , 6, .

In the second step, you should add $3c$ to the left side, not subtract $3c$ .
In the second step, you should add , 3 c, to the left side, not subtract , 3 c, .

In the second step, you should add $5c$ to each side, not $3c$ .
In the second step, you should add , 5 c, to each side, not , 3 c.
Question 2
Correct the error.

Answer 1

The error is in the second step, where you should add in both sides 3c, instead of subtracting 3 c.

The actual solution of the linear equation is c = 5/4.

Where is the mistake?

Here we have the equation:

5c - 6 = 4 - 3c

And the steps to solving this are:

2c - 6 = 4

2c = 10

c = 5

We can identify that the error is in the second line. If we go to the first equation and simplify it we get:

5c - 6 = 4 - 3c

5c + 3c - 6 = 4

8c -6 = 4

8c = 10

c = 10/8 = 5/4

The error is in the second step, where you should add in both sides 3c, instead of subtracting 3 c.

The actual solution of the linear equation is c = 5/4.
