Question

In this system of equations, x+3y=13 and 3x+2y=25 which variable would it be easiest to solve for? The easiest to solve for is x in the first equation. The easiest to solve for is y in the first equation. The easiest to solve for is x in the second equation. The easiest to solve for is y in the second equation.

Answer 1

It's A.

Explanation:

I just got it right on my quiz.

Answer 2

The easiest to solve for is x in the first equation.

Explanation:

In this system of equations, x+3y=13 and 3x+2y=25

LEts solve the first equation for x

x+3y=13

Subtract 3y on both sides

x = 13- 3y

so we solved for x easily

Lets check second equation and solve for x

3x+2y=25

Subtract 2y on both sides

3x= 25-2y

divide both sides by 3

x= 25/3 - 2y/3

WE are left with fraction , so solving for y is not an easy way

The easiest to solve for is x in the first equation because x is alone with no coefficients in the first equation
