Question

When solving the following system of equations, which variable would be the easiest to solve for?

5x + 3y = 22
4x - 2y = 16
Select the correct option:

A) The x in the second equation.
B) The y in the first equation.
C) The y in the second equation.
D) The x in the first equation.

Answer 1

The easiest variable to solve for is the x in the second equation.

Step-by-step explanation:

To solve the system of equations 5x + 3y = 22 and 4x - 2y = 16, the easiest variable to solve for is The x in the second equation (option A).

To solve for x, we can use the second equation since it only has one term with x. We can isolate x by moving the -2y term to the other side of the equation:

4x = 16 + 2y

Then, we divide both sides by 4 to solve for x:

x = (16 + 2y) / 4
