Malik used these steps to solve the system of equations. 2 x + 4 y = 20. 5 x minus 3 y = 11.

Step 1 6 x + 12 y = 60. 20 x minus 12 y = 44.
Step 2
Step 3 x = 4
Step 4 2 (4) + 4 y = 20. 8 + 4 y = 20. 4 y = 12. y = 3.
Step 5 The solution is (4, 3).

What needs to be done in step 2?
Divide both sides of the equations in step 1 by the same number to eliminate one variable.
Multiply both sides of the equations in step 1 by the same number to eliminate one variable.
Add the equations in step 1 to eliminate one variable.
Subtract the equations in step 1 to eliminate one variable.
