The solution to the system of equations using the elimination method is a = -2, b = 4, c = 3.

To solve the given system of equations using the elimination method, we can follow these steps:

Write both equations in standard form.

Multiply one or both equations by constants, if needed, to make the coefficients of a variable opposites.

Add or subtract the equations to eliminate a variable.

Solve for the remaining variable.

Substitute the value found back into one of the original equations to solve for the other variable.

Given the system:

6a+ 5b+c=5

5a3b-5c = -29

-2a-4b2c= -12

We can start by eliminating the variable ( c ). To do this, we can multiply the first equation by 2 and the third equation by 5, and then add the resulting equations to eliminate ( c ).

After solving for ( a ) and ( b ), we can substitute the values back into one of the original equations to solve for the remaining variable.

The solution to the system of equations using the elimination method is a = -2, b = 4, c = 3.
