Answer 2

Let's solve each equation step by step:

1. (x + 15) + 45 = 95

First, simplify the equation by removing the parentheses:

x + 15 + 45 = 95

Combine like terms:

x + 60 = 95

Next, isolate x by subtracting 60 from both sides:

x + 60 - 60 = 95 - 60

x = 35

Therefore, the solution for the first equation is x = 35.

2. (x - 10) - 15 = 38

Again, simplify the equation:

x - 10 - 15 = 38

Combine like terms:

x - 25 = 38

Next, isolate x by adding 25 to both sides:

x - 25 + 25 = 38 + 25

x = 63

Thus, the solution for the second equation is x = 63.

3. 109 - (x - 10) = 65

Once again, simplify the equation:

109 - (x - 10) = 65

Distribute the negative sign to the terms inside the parentheses:

109 - x + 10 = 65

Combine like terms:

119 - x = 65

To isolate x, subtract 119 from both sides:

119 - x - 119 = 65 - 119

-x = -54

Multiply both sides by -1 to change the sign of x:

(-1)(-x) = (-1)(-54)

x = 54

Therefore, the solution for the third equation is x = 54.

In summary, the solutions for the given equations are:

1. x = 35
2. x = 63
3. x = 54
