M=cost of Manx; R=cost of Russian Blue=M+$150
.
9R+8M=$14100
9(M+$150)+8M=$14100
9M+$1350+8M=$14100
17M=$12750
M=$750

.
R=M+$150=$750+$150=$900

A Russian Blue kitten costs $150 more than a Manx kitten. 9 Russian Blue kittens and 8 Manx kittens cost $14 100 in total.
-------------
RB = MX + 150
9RB + 8MX = 14100
--------------------------
Substitute for "RB" and solve for MX::
9(MX + 150) + 8MX = 14100
17MX = 14100-9*150
---
MX = $750
RB = 750+150 = $900.00
---------
