Question

What is the solution of the system of equations?

y = –5x + 6
y = –3x – 4

Answer 1

Answer:

(x, y) - (5, -19)

Step-by-step explanation:

Equate the two expressions for y:

... -5x +6 = -3x -4

... 10 = 2x . . . . . . . . add 5x+4

... 5 = x . . . . . . . . . . divide by 2

... y = -3·5 -4 = -19 . . . . use one of the equations to find y
