18/6 = 3
24/6 = 4
Think of it as a fraction. All you have to do is divide by a common number that matches both sides.

Let's manipulate this into the y=mx + b form.
Add 4x to both sides
-6y = 4x + 24
Divide both sides by -6
Just use the slope to find the points you need.
The y-intercept is (0,-4).
The slope is
(-6,0)
You could have also used the slope intercept method.
-4(0) - 6y = 24
-6y = 24
Divide both sides by -6
y = -4
(0,-4)
-4x - 6(0) = 24
-4x = 24
Divide both sides by -4
x = -6
(-6,0)
Since 6y does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 6y from both sides.
−4x=−6y+24
Divide each term in the equation by −4.
−4x/−4=−6y/−4+24/−4
Simplify
x=3y/2+24/−4
Divide 24 by −4 to get −6.
x=3y/2−6
x is equal to 3y/2−6
You solve y the same way you solve x:
Because −4x does not contain the variable to solve for, move it to the right-hand side of the equation by adding 4x to both sides.
6y=4x+24
Divide each term in the equation by 6.
6y/6=4x/6+24/6
Simplify
y=2x/3+24/6
Divide 24 by 6 to get 4.
y=2x/3+4
y is equal to 2x/3+4

Yes, only number 2 is correct.
Your number 4 seems to only consist of a. Hence, I can't make any assumptions based on that.
So yes, only number 2 is correct.

Set it up as 15x-13+8x+29+2y=180 and then just find a algebra calculator and put that formula in there
This triangle is an isosceles triangle. That means that the two base angles are equal.
You can set the two expressions equal to each other.
15x-13=8x+29
Solving this, you will find that x=6
Now you can plug x into the two expressions.
15(6)-13=77
8(6)+29=77
Those are the measurements of the two angles.
To find the last angle, you know that the angles of any triangle add up to 180 degrees. Using this information, you can add up the 3 angle measurements and set them equal to 180.
77+77+2y=180
y=13
Now plug in y.
2(13)=26
THe three angle measures are 77, 77, and 26

4x -2y =22
2x + 4y = 6
Answers
4x -2y =22------> clear variable y
2y=4x-22--------> y=4x/2-22/2---------> y=2x-11-----> equation 1
2x + 4y = 6------> equation 2
substitute equation 1 in equation 2
2x+4*[2x-11]=6-----> 2x+8x-44=6----> 10x=50------> x=5
then
y=2x-11----> y=2*5-11----> y=-1
