Answer 2

To solve the equation, let's break it down into three separate equations:

1. 10 - 7X = 7 - XT
2. T + 6.8 = 9T + 101
3. 2.6Z = 6 + 3Z

Let's solve them one by one:

1. 10 - 7X = 7 - XT

To solve this equation, let's collect all the terms with X on one side and all the terms with T on the other side:

-7X + XT = 7 - 10

Next, factor out X and T:

X(-7 + T) = -3

Now, divide both sides by (-7 + T):

X = -3 / (-7 + T)

2. T + 6.8 = 9T + 101

Let's simplify the equation:

6.8 = 8T + 101

Move the constants to one side and the variable term to the other side:

8T - T = 101 - 6.8

Combine like terms:

7T = 94.2

Divide both sides by 7:

T = 94.2 / 7

T ≈ 13.457

3. 2.6Z = 6 + 3Z

Move the Z terms to one side and the constant term to the other side:

2.6Z - 3Z = 6

Combine like terms:

-0.4Z = 6

Divide both sides by -0.4:

Z = 6 / -0.4

Z = -15

Therefore, the solutions to the given equations are: X = -3 / (-7 + T) T ≈ 13.457 Z = -15
