7%2Fw%2B45%2Fw%2B4=6%2Fw
Multiply by w both sides of the equation
w%287%2Fw%2B45%2Fw%2B4%29=w%286%2Fw%29
7w%2Fw%2B45w%2Fw%2B4w=6w%2Fw

7%2B45%2B4w=6
52%2B4w=6
4w=6-52
4w=-46
Divide by 4 both sides of the above equation
4w%2F4=-46%2F4
cross%284%29w%2Fcross%284%29=-cross%2846%29%2Fcross%284%29
w=-23%2F2
w=-%2811%261%2F2%29
