Question

2/3-x=2/3; 6/3+n=9/8; d+6/5=1/5.

Answer 1

1. х= 0
2. n=7/8
3. d=1

Answer 2

Let's solve each of these equations step-by-step:

1. 2/3 - x = 2/3

To isolate x on one side of the equation, we need to get rid of the term with x on the left side. We can achieve this by performing inverse operations:

Step 1: Subtract 2/3 from both sides of the equation.

2/3 - 2/3 - x = 2/3 - 2/3
-x = 0

Step 2: Divide both sides by -1 to solve for x.

x = 0

So the solution to the first equation is x = 0.

2. 6/3 + n = 9/8

Similarly, we need to isolate n on one side of the equation:

Step 1: Simplify the left side of the equation.

6/3 + n = 2 + n

Step 2: Subtract 2 from both sides of the equation.

2 + n - 2 = 9/8 - 2
n = 9/8 - 16/8
n = -7/8

So the solution to the second equation is n = -7/8.

3. d + 6/5 = 1/5

To isolate d on one side of the equation:

Step 1: Subtract 6/5 from both sides of the equation.

d + 6/5 - 6/5 = 1/5 - 6/5
d = -5/5

Step 2: Simplify the right side of the equation.

d = -1

So the solution to the third equation is d = -1.

In summary:

1. x = 0
2. n = -7/8
3. d = -1
