Question

solve the system using substitution write your final answer as a coordinate point

5x - y = 4

2x + 2y = 16

Answer 1

Answer:

x=2 and y=6;   (2,6) are coordinate points

Step-by-step explanation:

5x-y=4........i)

2x+2y=16.....ii)

multiply eq.i) by 2

10x-2y=8...iii)

add eq ii and iii

10x-2y+2x+2y=8+16

12x=24

x=2

put x=2 in eq i

5(2)-y=4

10-4=y

6=y
