Answer:
x=8
Step-by-step explanation:
x + 1 = 9
Simplifying
x + 1 = 9
Reorder the terms:
1 + x = 9
Solving
1 + x = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + x = 9 + -1
Combine like terms: 1 + -1 = 0
0 + x = 9 + -1
x = 9 + -1
Combine like terms: 9 + -1 = 8
x = 8
Simplifying
x = 8
I think 28 (2x16) = 32 -4 + 28
Well, lets start with #3!
<1 is equivalent to <3 because they are vertical angles.
This means that <2 and <4 are congruent because they are vertical angles. We know that a straight line is 180 degrees. So, <1 and <2 added together will equal 180, therefore, <2 is ___________
Since the two lines are parallel, any angle on the other side is congruent, as long as that angle is in the same place as the other. So, we can see that <1 and <7 are in the same place, just moved down. So, <7 is __________.
Answer:

Step-by-step explanation:
So we have:

Remove all the fractions to make things simpler. To do so, we can multiply by the LCM of the denominators.
The denominators are 3 and 7.
The LCM of 3 and 7 is 21. Thus, multiply everything by 21:

Distribute:

Simplify the fractions:

Add 12x to both sides:

Subtract 9 from both sides:

Divide both sides by 26:

Reduce:

And that's our answer :)
