Question

At what value of x do the graphs of the equations below intersect?

2x − y = 6

5x + 10y = −10

Answer 1

Answer:

Step-by-step explanation:

2x - y = 6

5x + 10y = -10

( 2x - y = 6 ) * 5

10x - 5y = 30

( 5x + 10y = -10 ) * 2

10x + 20y = -20

If we subtract the last 2 equations,

30y = -50

y = -(5/3)

2x - (-5/3) = 6

2x + (5/3) = 6

2x = 6 - (5/3)

2x = (18-5)/3

2x = 13/3

x = 13/6
