10x-35+3ax=5ax-7a
10x-35=5ax-7a-3ax
10x-35=a(5x-7-3x)
(10x-35)/(5x-7-3x)=a


therefore a=(10x-35)/(5x-7-3x)

Answer:

[tex]a=\frac{10x-35}{2x-7}[/tex]

Step-by-step explanation:

We have been given an equation [tex]10x-35+3ax=5ax-7a[/tex]. We are asked to solve the given equation for 'a'.

Switch sides:

[tex]5ax-7a=10x-35+3ax[/tex]  

[tex]5ax-3ax-7a=10x-35+3ax-3ax[/tex]  

[tex]2ax-7a=10x-35[/tex]

Factor out a:  

[tex]a(2x-7)=10x-35[/tex]  

Divide both sides by [tex](2x-7)[/tex]:

[tex]\frac{a(2x-7)}{(2x-7)}=\frac{10x-35}{(2x-7)}[/tex]

[tex]a=\frac{10x-35}{2x-7}[/tex]

Therefore, our required equation would be [tex]a=\frac{10x-35}{2x-7}[/tex].
