Jambmaths question:
Find the range of values of x for which $\frac{x+2}{4}-\frac{2x-3}{3}<4$
Option A:
$x>-6$
Option B:
$x>-3$
Option C:
$x<8$
Option D:
$x<4$
Jamb Maths Solution:
$\begin{align} & \frac{x+2}{4}-\frac{2x-3}{3}<4 \\ & \frac{3(x+2)-4(2x-3)}{12}<4 \\ & \frac{3x+6-8x+12}{12}<4 \\ & -5x+18<48 \\ & -5x<30 \\ & x>-6 \\\end{align}$
