Expand the brackets first
5(wx-v) = 9(x + v) 
5wx - 5v = 9x + 9v

Get all x's on one side and everything on on the other side
9x - 5wx = 9v + 5v

factorise out the x
x(9-5w) = 14v

then divide by 9-5w
x = 14v/(9-5w)

5(wx-v)=9(x+v)\\
5wx-5v=9x+9v\\
5wx-9x=14v\\
x(5w-9)=14v\\
x=\frac{14v}{5w-9}

Olin [163]

Answer:

d=9.2

Step-by-step explanation:

Distance Formula: d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

d=\sqrt{(1-8)^2+(1-(-5))^2}

d=\sqrt{(-7)^2+(1+5)^2}

d=\sqrt{49+(6)^2}

d=\sqrt{49+36}

d=\sqrt{85}

d=9.21954

d=9.2
