Answer:
see below
Step-by-step explanation:
10 markers =7 dollars
Divide each side by 10
10/10 = 7 /10
1 marker = 7/10
y =7/10 x where y is the cost and x is the number of markers
24 markers =14 dollars
Divide each side by 24
24/24 = 14 /24
1 marker = 7/12
y = 7/12 x where y is the cost and x is the number of markers
Solving the expression
we get value of x: 
Step-by-step explanation:
We need to solve the equation
and find value of x
Solving:
![-[-2(x-4) - |1-3|] = -2x18](https://tex.z-dn.net/?f=-%5B-2%28x-4%29%20-%20%7C1-3%7C%5D%20%3D%20-2x18)
Multiply -2 with terms inside the bracket
![-[-2x+8 - |1-3|] = -2x18](https://tex.z-dn.net/?f=-%5B-2x%2B8%20-%20%7C1-3%7C%5D%20%3D%20-2x18)
Solving |1-3| we get |-2|=2
![-[-2x+8 - 2] = -2x18](https://tex.z-dn.net/?f=-%5B-2x%2B8%20-%202%5D%20%3D%20-2x18)
![-[-2x+6] = -2x18](https://tex.z-dn.net/?f=-%5B-2x%2B6%5D%20%3D%20-2x18)
Multiply (-) sign with terms inside the bracket

Multiply 2x with 18

Add 36x on both sdides


Add 6 on both sides:

Divide both sides by 38

Simplifying:

So, Solving the expression
we get value of x:

Answer:
5x + 6y = -14
Step-by-step explanation:
Standard form means the x term will be on the farthest left, then the y term next, set equal to the constant (plain number) all by itself on the right.
Like this:
Ax + By = C
So you have
-5x - 14 = 6y
Add 14 to both sides.
-5x = 6y + 14
Subtract 6y from both sides.
-5x - 6y = 14
Also multiply both sides by -1, to make sure your A value (number next to the x) is positive.
5x + 6y = -14
