Question

How do you solve 2x + 5y = 13 and y = –2x + 17?

Answer 1

Answer:

Step-by-step explanation:

2x+5y=13...............(1)

y=-2x+17...................(2)

Substituting (2) in (1)

2x+5(-2x+17)=13

2x+(-10x+85)=13

-8x=-72

x=9

Substituting the value of x in (2),

y=-2x9+17

y=-18+17=-1

x=9 & y= -1
