Question

Elimination



x-9y= -10
6x-3y=-9

Answer 1

x = -1, y = 1

Explanation:

To solve by elimination, first multiply x - 9y = -10 by 6 to get the same coefficient on x in each equation. Then subtract each like term.

6x - 54y = -60

6x - 3y = -9

-----------------------

-51y = -51

y = 1

Substitute y= 1 into one equation and solve for x.

x - 9y = -10

x -9(1) = -10

x - 9 = -10

x = -1
