The sum of two adjacent angles is 100 degrees, so we can write the equation:

<1 + <2 = 100

Given that <1 = 20 degrees and <2 = (3x + 15), we can substitute these values into the equation:

20 + (3x + 15) = 100

Simplifying the equation, we have:

35 + 3x = 100

To solve for x, we can subtract 35 from both sides:

3x = 100 - 35

3x = 65

Finally, dividing both sides by 3, we get the equation:

x = 65/3

So, the equation to solve for x is x = 65/3.

Apologies for the incorrect response. You are correct, the equation should be:

3x + 35 = 100

To solve for x, we can isolate the variable by subtracting 35 from both sides:

3x = 100 - 35

3x = 65

Finally, dividing both sides by 3, we get the equation:

x = 65/3

So, the correct equation to solve for x is x = 65/3.

To solve for x in the equation 5x + 12 = 112, we need to isolate the variable x.

First, we subtract 12 from both sides:

5x = 112 - 12

5x = 100

Next, divide both sides by 5:

x = 100 / 5

x = 20

Therefore, the equation 5x + 12 = 112 can be solved by x = 20.
