Here is a system of linear equations: Select all the steps that would help to eliminate a variable and enable solving.

• Multiply the first equation by 2, then subtract the second equation from the result.
• Multiply the first equation by 4 and the second equation by 6, then subtract the resulting equations.
• Multiply the first equation by 2, then add the result to the second equation.
• Divide the second equation by 2, then add the result to the first equation.
• Multiply the second equation by 6, then subtract the result from the first equation.
