Answer:

x = 5y + 9

Step-by-step explanation:

2x - 10y = 18

2x = 18 + 10y (add 10y to both sides)

x = 9 + 5y (divide both sides by 2 to isolate the variable)

x = 5y + 9 (just reorder to have the variable first)

Answer:

x = [tex]\frac{10y + 18}{2}[/tex]

s = [tex]\frac{n}{2}[/tex]

Step-by-step explanation:

2x - 10y = 18

2x = 10y + 18

x = [tex]\frac{10y + 18}{2}[/tex]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

n = [tex]\frac{s+360}{180}[/tex]

180n = s + 360

s = 180n/360

s = [tex]\frac{n}{2}[/tex]
