Question

Here is a system of equations: 6.2 -y= 18 4x + 2y = 26 Select all the steps that would help to eliminate a variable and enable solving. Divide the second equation by 2. then add the result to the first equation. Multiply the first equation by 2. then add the result to the second equation. Multiply the first equation by 4 and the second equation by 6, then subtract the resulting equations. O Multiply the second equation by 6, then subtract the result from the first equation. Multiply the first equation by 2. then subtract the second equation from the result.

Answer 1

to eliminate the variable y

we have steps are,

1) Divide the second equation by 2. then add the result to the first equation

or

2) Multiply the first equation by 2. then add the result to the second equation

or

3) Multiply the first equation by 4 and the second equation by 6, then subtract the resulting equations.

so the answer is the first three options.
