Assessment: JAMB UTME - Mathematics - 2010 Subject: General Mathematics

Question 1 Report

For what range of values of x is $\frac{1}{2}$ x + $\frac{1}{4}$ > $\frac{1}{3}$ x + $\frac{1}{2}$ ?

x <

\frac{3}{2}

x >

\frac{3}{2}

x < -

\frac{3}{2}

x > -

\frac{3}{2}

Answer Details

$\frac{1}{2}$ x + $\frac{1}{4}$ > $\frac{1}{3}$ x + $\frac{1}{2}$
Multiply through by through by the LCM of 2, 3 and 4
12 x $\frac{1}{2}$ x + 12 x $\frac{1}{4}$ > 12 x $\frac{1}{3}$ x + 12 x $\frac{1}{2}$
6x + 3 > 4x + 6
6x - 4x > 6 - 3
2x > 3
$\frac{2 x}{2}$ > $\frac{3}{2}$
x > $\frac{3}{2}$
