Hello there!
4(3x - 11) + 23 = 5x - 14
Apply the distributive property to 4(3x - 11)
4(3x) + 4(-11)
12x - 44
We now have:
12x - 44 + 23 = 5x - 14
Combine like-terms on the left-hand side of the equation.
-44 + 23 = -21
12x - 21 = 5x - 14
Get x on one side by subtracting 5x from both sides..
12x - 5x = 7x
5x - 5x = 0
7x - 21 = -14
Add 21 to both sides to isolate 7x.
-21 + 21 = 0
-14 + 21 = 7
7x = 7
Divide both sides by 7 to solve for x.
7x / 7 = x
7 / 7 = 1
We are now left with the following solution:
x = 1
I hope this helps!

Answer:
x≈ -4.71
Step-by-step explanation:
7(x+6)=9
Distribute the 7 into the parenthesis.
7x+ 7(6)= 9
Multiply the numbers.
7x+ 42= 9
Subtract from both sides.
7x+42= 9
-42 -42
Now, divide to both sides.
<u> 7x</u>= <u>-33</u>

<h2>x = 54</h2>
Step-by-step explanation:
The line is tangent. Therefore, the angle between the tangent and the radius is the right angle.
We know: the sum of the angles measures in a triangle is 180°.
Therefore we have the equation:
<em>combine like terms</em>
<em>subtract 126 from both sides</em>
