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.
Answer:
b=-0.75a+2
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}
3a−7
4b−1
