10-41.

Victoria is playing with her balance scale and balances 3 blue blocks and 2 red blocks on one side with 5 blue blocks and a red block on the other. Later, her brother balances 2 red blocks and a blue block with a 40-gram weight. How much does each block weigh? Homework Help ✎

Create a system of equations to solve the problem.

Where *r* is the weight of a red block, and *b* is the weight of a blue block:

3*b* + 2*r* = 5*b* + *r*

2*r* + *b* = 40
