• Khobar: 31 c 30 c 30 c 30 c 30 c 31 c 31 c 32 c
• Jeddah: 32 c 36 c 35 c 35 c 24 c 34 c 33 c 33c
• ﻿I know how to do it!!
• ﻿X= Khobar Y= Jeddah 1. make equations X+Y=65 5X+3Y=257 2. Make matricies |1 1| |x| = |65| |53| |y| = |257| 3. use matrix inverse 1/ad-bc |d -b| |-c a| 1\(1x3)-(1x5) |3 -1| |-5 1| |x|= |-1.5 0.5| |65| |y|= |2.5 -0.5| 257| 4. multiply 1st row for X -1.5x65+0.5x257= 31 5. multiply 2nd row for y 2.5x65+-0.5x257= 34
