Question

Solve this system of linear equations. Separate
the x- and y-values with a comma.
5x + 2y = 13
-9x + 7y = 19

Answer 1

Answer:

A) 5x + 2y = 13

B) -9x + 7y = 19 We'll multiply equation A) by -(7/2)

A) -35/2 x -7y = -(91/2) then we'll add equation B)

B) -9x + 7y = 19

-53/2x = -53/2

x = 1

2y = 13 -5

y = 4
