Question

26 What is the value of x in the solution to the system of equations below?

6x + 3y = 13
3x - y = 4

Answer 1

5/3

Explanation:

I will solve by elimination.

1) Make the constant next to y in one equation the opposite of the other equation:

(3x-y+4)3

9x-3y+12

2) Add equations:

6x+3y=13

9x-3y=12

15x=25

x=25/15

x=5/3
