Answer:

Step-by-step explanation:

Given that

-3a+6b=a+4b

We want to make b subject of formula

First to remove the 4b in the Right hand side of the equation

Subtract 4b from both side of the equation

-3a+6b-4b=a+4b-4b

Then we have,

-3a+2b=a

Now to remove the -3a from the left hand side of the equation add 3a to both side

Then,

-3a+2b+3a=a+3a

2b-3a+3a=4a

Then, 2b=4a

Divide both side by 2

2b/2=4a/2

b=2a.

Step-by-step explanation:

o arrive at a correct equation, we have to solve the equation for bbb.

Hint #22 / 3

\begin{aligned}3a-7&=-4b+1\\\\ 4b-1&=7-3a\\\\ 4b&=8-3a\\\\ b&=\dfrac{8}{4}-\dfrac{3a}{4}\\\\ b&=2-\dfrac{3}{4}a\end{aligned}
