Question

In this system of equations, which variable would it be easiest to solve for?

x + 3 y = 13.
3 x + 2 y = 25.

Answer 1

Answer:x=7& y= 2

Explanation:

x+3y=13

3x+2y=25

Using elimination method

We have

3× x+3y=13......I

1×3x+2y=25....ii

3x+9y=39

3x+2y=25

7y=14

Divide through by 7

y=2

Substitute for y in equation i

x+3(2)=13

x+6=13

x=7
