The "step 2" that Malik should take in order to solve the given system of equations is to add both equations.
Given to us
Step 1: Multiply the first equation with 3, while the second equation with 4,
6x + 12 y = 60
20x - 12 y = 44
Step 2: Add both the equations,
(6x + 12y) + (20x - 12y) = 60+44
Step 3: caluculate the value of x,
x = 4
Step 4: Substitute the value of x in equation 1,
2(4) + 4y = 20
8 + 4y = 20.
4y = 12
Y = 3
Step 5: The solution is (4, 3).
Hence, the "step 2" that Malik should take in order to solve the given system of equations is to add both equations.

You mean five thousand and eight hundred? If so, then the answer is = 5800
X + y = 24....multiply by -3
3x + 5y = 100
---------------
-3x - 3y = - 72 (result of multiplying by -3)
3x + 5y = 100
----------------add
2y = 28
y = 28/2
y = 14 <== 5 pointers
x + y = 24
x + 14 = 24
x = 24 - 14
x = 10 <== 3 pointers
The answer is 21 which comes from 7 * 3.
Draw the four points in a complex plane. From the drawing you can see that the lenght is 4i - (-3i) = 4i + 3i = 7i, and the width is 1 - (-2) = 1 + 2 = 3.
So, the area is 7 * 3 = 21.
