Question

a ) $\frac{x+2}{3} -2= \frac{x-1}{2}$
b ) $-3(2x+18-39)=-6+8x$

Answer 1

$\displaystyle a). \frac{x+2}{3} -2= \frac{x-1}{2} \\ 2(x+2)-2 \cdot 6=3(x-1) \\ 2x+4-12=3x-3 \\ 2x-3x=-3-4+12 \\ -x=5 \Rightarrow x=-5 \\ b).-3(2x+18-39)=-6+8x \\ -3(2x-21)=-6+8x \\ -6x+63=-6+8x \\ -6x-8x=-6-63 \\ -14x=-69 \Rightarrow x= \frac{69}{14}$
