Question

Solve the following systems of equations. Express your answer as an ordered pair in the format (a,b), with no spaces between the numbers or symbols. 3x+4y=16 -4x-3y=-19

Answer 1

(4, 1)

Explanation:

3x+4y=16 /*4

-4x-3y= - 19 /*3

12x + 16y = 64

- 12x - 9y = - 57

7y = 7

y = 1

3x+4y=16

3x + 4*1 = 16

3x = 16 - 4

3x = 12

x = 4
