Make x the subject of these equations. Thanks ^^
9x+v=4x+w

ax+4=3x+b

5x-w=vx+y

7-wx=vx+1

5(wx-v)=8(x+v)

x=w-v/13

x=b-4/(a-3)

x=y+w/(5-v)

x=6/(v+w)

x=13v/(5w-8)

Step-by-step explanation:

We are to make x the subject of formula

So let's solve

9x+v=4x+w

Let's collect like terms

9x-4x=w-v

13x=w-v

Divide both sides by 13

x=w-v/13

ax+4=3x+b

Collect like terms

ax-3x=b-4

x(a-3)=b-4

x=b-4/(a-3)

5x-w=vx+y

Collect like terms

5x-vx=y+w

x(5-v)=y+w

x=y+w/(5-v)

7-wx=vx+1

Collect like terms

7-1=vx+wx

6=x(v+w)

x=6/(v+w)

5(wx-v)=8(x+v)

Open the bracket

5wx-5v=8x+8v

Collect like terms

5wx-8x=8v+5v

x(5w-8)=13v

x=13v/(5w-8)
