I see you're probably trying to use a math editor to present this problem. Unfortunately, I'm unsure how to decipher your "-\frac {a }{8.06)." What fraction are you speaking of?
Given "<span>#-\frac { a } { 8.06} + 7.02= 18.4#," all I can say with certainty is that you could legitimately subtract 7.02 from both sides:
</span><span>#-\frac { a } { 8.06} + 7.02= 18.4#
- 7.02 = -7.02
After I've heard back from you, I'll try to help you solve the entire problem.

Its the same slope and everything just move the y intercept to 4
Think its false bc they can do anything buy answering the questions
Answer:

Step-by-step explanation:
The angles in a triangle must add to 180 degrees.
We are given three angles: 2x+6, x, and 3x. Their sum must be 180, so we can create an equation.

Combine like terms (all terms with an x) on the left side.


Now solve for x by isolating the variable.
6 is being added and the inverse of addition is subtraction. Subtract 6 from both sides.

x is being multiplied by 6. The inverse of multiplication is division. Divide both sides by 6.

Substitute 29 for x in the angle measures.
- 2x+6= 2(29)+6=58+6=<u>64</u>
- x=<u>29</u>
- 3x= 3(29)=<u>87</u>
<u></u>
The largest angle is 87 degrees.
