Question

Solve this system of linear equations. Separate

the x- and y-values with a comma.
13x = -54 - 20y
- 10x = 60 + 20y
Enter the correct answer.

Answer 1

x 2 y -4

Explanation:

13x = -54 -20y give it is A

-10x = 60 + 20y give it is B

A + B the sum of the left side of equation is equal to the sum of the right side of equation

13 + (-10x) = -54 -20y + 60 + 20y

3x = 60-54

3x = 6

x=2

so put the x value in A or B equation you can receive y value (B is easier)

y = -4
