1. Algebra

I have this equation

$[1-c_1(1-t_1)+m_1]Y = c_0 -c_1 t_0 + I + G + X - m_0$

which rearranged gives this equation.

$Y = \frac{1}{1-c_1 (1-t_1)+m_1}[c_0 -c_1 t_0 + I + G + X - m_0]$

I cant work out where they got $\frac{1}{1-c_1 (1-t_1)+m_1}$

i keep getting this

$Y = \frac{c_0 -c_1 t_0 + I + G + X - m_0}{1-c_1(1-t_1)+m_1}$
Could someone please enlighten me.

it's the same thing ...

$ab = c$

to isolate $b$ , multiply both sides by the multiplicative inverse of $a$ ...

$\frac{1}{a} \cdot ab = \frac{1}{a} \cdot c$

$b = \frac{1}{a} \cdot c = \frac{c}{a}$

3. right lol thanks.
