Solve the system of equations. 4x+3y+6z=3 5x+5y+6z=5 6x+3y+6z=3

C.

Step-by-step explanation:

Consider the system of three equations:

Multiply the first equation by 5, the second equation by 4 and subtract them:

Multiply the first equation by 3, the second equation by 2 and subtract them:

Multiply the second equation by 3, the third equation by 5 and add the second and the third equations:

Fro mthe third equation

Substitute it into the second equation:

Substitute y=1 and z=0 into the first equation:

The solution is

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
