Assessment: JAMB UTME - Mathematics - 2003 Subject: General Mathematics

Question 1 Report

Find the range of the value of x satisfying the inequalities 5 + x $\leq$ 8 and 13 + x $\geq$ 7

-3 $\leq$ x $\leq$ 3

3 $\leq$ x $\leq$ 6

-6 $\leq$ x $\leq$ 3

-6 $\leq$ x $\leq$ -3

Answer Details

5 + x $\leq$ 8 and 13 + x $\geq$ 7
5 + x $\leq$ 8
X $\leq$ 8 – 5
X $\leq$ 3
And 13 + x $\geq$ 7
X $\geq$ 7 – 15
X $\geq$ -7
Combining the two together
-6 $\leq$ x $\leq$ 3
